Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712756, here are decompositions:

5 + 8712751 = 8712756
7 + 8712749 = 8712756
29 + 8712727 = 8712756
43 + 8712713 = 8712756
47 + 8712709 = 8712756
79 + 8712677 = 8712756
127 + 8712629 = 8712756
179 + 8712577 = 8712756

Showing the first eight; more decompositions exist.
