Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724756, here are decompositions:

17 + 8724739 = 8724756
37 + 8724719 = 8724756
43 + 8724713 = 8724756
59 + 8724697 = 8724756
107 + 8724649 = 8724756
113 + 8724643 = 8724756
137 + 8724619 = 8724756
167 + 8724589 = 8724756

Showing the first eight; more decompositions exist.
