Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655912, here are decompositions:

11 + 8655901 = 8655912
29 + 8655883 = 8655912
43 + 8655869 = 8655912
53 + 8655859 = 8655912
71 + 8655841 = 8655912
103 + 8655809 = 8655912
151 + 8655761 = 8655912
163 + 8655749 = 8655912

Showing the first eight; more decompositions exist.
