Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601128, here are decompositions:

7 + 8601121 = 8601128
31 + 8601097 = 8601128
157 + 8600971 = 8601128
181 + 8600947 = 8601128
229 + 8600899 = 8601128
409 + 8600719 = 8601128
499 + 8600629 = 8601128
541 + 8600587 = 8601128

Showing the first eight; more decompositions exist.
