Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655998, here are decompositions:

7 + 8655991 = 8655998
31 + 8655967 = 8655998
61 + 8655937 = 8655998
79 + 8655919 = 8655998
97 + 8655901 = 8655998
139 + 8655859 = 8655998
157 + 8655841 = 8655998
229 + 8655769 = 8655998

Showing the first eight; more decompositions exist.
