Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651764, here are decompositions:

41 + 8651723 = 8651764
47 + 8651717 = 8651764
53 + 8651711 = 8651764
71 + 8651693 = 8651764
101 + 8651663 = 8651764
137 + 8651627 = 8651764
227 + 8651537 = 8651764
257 + 8651507 = 8651764

Showing the first eight; more decompositions exist.
