Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655764, here are decompositions:

3 + 8655761 = 8655764
31 + 8655733 = 8655764
43 + 8655721 = 8655764
127 + 8655637 = 8655764
307 + 8655457 = 8655764
331 + 8655433 = 8655764
421 + 8655343 = 8655764
433 + 8655331 = 8655764

Showing the first eight; more decompositions exist.
