Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712856, here are decompositions:

29 + 8712827 = 8712856
107 + 8712749 = 8712856
179 + 8712677 = 8712856
227 + 8712629 = 8712856
359 + 8712497 = 8712856
563 + 8712293 = 8712856
569 + 8712287 = 8712856
587 + 8712269 = 8712856

Showing the first eight; more decompositions exist.
