Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655900, here are decompositions:

17 + 8655883 = 8655900
23 + 8655877 = 8655900
31 + 8655869 = 8655900
41 + 8655859 = 8655900
59 + 8655841 = 8655900
131 + 8655769 = 8655900
139 + 8655761 = 8655900
151 + 8655749 = 8655900

Showing the first eight; more decompositions exist.
