Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655518, here are decompositions:

61 + 8655457 = 8655518
97 + 8655421 = 8655518
211 + 8655307 = 8655518
307 + 8655211 = 8655518
577 + 8654941 = 8655518
601 + 8654917 = 8655518
709 + 8654809 = 8655518
757 + 8654761 = 8655518

Showing the first eight; more decompositions exist.
