Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724750, here are decompositions:

11 + 8724739 = 8724750
29 + 8724721 = 8724750
31 + 8724719 = 8724750
37 + 8724713 = 8724750
53 + 8724697 = 8724750
101 + 8724649 = 8724750
107 + 8724643 = 8724750
109 + 8724641 = 8724750

Showing the first eight; more decompositions exist.
