Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656028, here are decompositions:

37 + 8655991 = 8656028
61 + 8655967 = 8656028
109 + 8655919 = 8656028
127 + 8655901 = 8656028
151 + 8655877 = 8656028
307 + 8655721 = 8656028
349 + 8655679 = 8656028
379 + 8655649 = 8656028

Showing the first eight; more decompositions exist.
