Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87568, here are decompositions:

11 + 87557 = 87568
29 + 87539 = 87568
59 + 87509 = 87568
251 + 87317 = 87568
269 + 87299 = 87568
311 + 87257 = 87568
317 + 87251 = 87568
347 + 87221 = 87568

Showing the first eight; more decompositions exist.
