Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12556, here are decompositions:

3 + 12553 = 12556
17 + 12539 = 12556
29 + 12527 = 12556
53 + 12503 = 12556
59 + 12497 = 12556
83 + 12473 = 12556
179 + 12377 = 12556
227 + 12329 = 12556

Showing the first eight; more decompositions exist.
