Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656662, here are decompositions:

59 + 8656603 = 8656662
73 + 8656589 = 8656662
89 + 8656573 = 8656662
101 + 8656561 = 8656662
139 + 8656523 = 8656662
151 + 8656511 = 8656662
163 + 8656499 = 8656662
181 + 8656481 = 8656662

Showing the first eight; more decompositions exist.
