Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655804, here are decompositions:

43 + 8655761 = 8655804
71 + 8655733 = 8655804
83 + 8655721 = 8655804
97 + 8655707 = 8655804
103 + 8655701 = 8655804
127 + 8655677 = 8655804
151 + 8655653 = 8655804
163 + 8655641 = 8655804

Showing the first eight; more decompositions exist.
