Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712550, here are decompositions:

3 + 8712547 = 8712550
17 + 8712533 = 8712550
53 + 8712497 = 8712550
59 + 8712491 = 8712550
179 + 8712371 = 8712550
227 + 8712323 = 8712550
239 + 8712311 = 8712550
257 + 8712293 = 8712550

Showing the first eight; more decompositions exist.
