8 8's make 1000

Question

Print the following output of a happy coincidence addition pattern:

Rules:

No leading spaces except the ones already present
There can be a trailing newline
+ sign needs to be displayed
Order of parcels needs to be the same

No winner. It is code-golf per language.

So, what exactly do you want us to print? 1000? 8+8+8+88+888=1000? — Okx, Nov 1, 2017 at 17:33
Ah, I got confused by the lack of the tag kolmogorov-complexity — Okx, Nov 1, 2017 at 17:43
I downvoted this challenge for the following reason: The output is far too short (in my opinion) for a KC challenge, and doesn't have a great pattern either. This doesn't leave too much place for clever compression, and hardcoding is most likely the golfiest way to solve it (in most languages). — Mr. Xcoder, Nov 1, 2017 at 17:57
I upvoted because with answers getting below the size of the plain output (34 bytes), there obviously are some "clever" ways. — Felix Palmen, Nov 2, 2017 at 9:59

,'   8'*3+"  88
+888"+'-'*4+1e3

Try it online!

Five bytes shorter than printing the string as-is, ~~but still not very golfy.~~ now getting to be golfy.

Constructs an array of 3x ' 8' (saving a byte), then array-concatenates the remaining items, with '-'*4 saving a byte. The other byte savings comes from using 1e3 in place of 1000.

\$\begingroup\$ You can replace all + on line breaks. This will not change the length. Only for fun. \$\endgroup\$

I use the a command to append text lines to output. For comparison, the trivial solution is to print the hardcoded text like below, 42 bytes. Reduction is 11.9 %.

v->"   8\n   8\n   8\n  88\n+888\n----\n1000"

Boring hard-coded output, but this can't be done any shorter in Java. Just utilizing the repeated part " 8\n" is already 52 bytes..
v->"aaa 88\n+888\n----\n1000".replace("a"," 8\n")
