Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655810, here are decompositions:

41 + 8655769 = 8655810
61 + 8655749 = 8655810
71 + 8655739 = 8655810
89 + 8655721 = 8655810
103 + 8655707 = 8655810
109 + 8655701 = 8655810
131 + 8655679 = 8655810
139 + 8655671 = 8655810

Showing the first eight; more decompositions exist.
