Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655712, here are decompositions:

5 + 8655707 = 8655712
11 + 8655701 = 8655712
41 + 8655671 = 8655712
59 + 8655653 = 8655712
71 + 8655641 = 8655712
83 + 8655629 = 8655712
89 + 8655623 = 8655712
101 + 8655611 = 8655712

Showing the first eight; more decompositions exist.
