Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660688, here are decompositions:

5 + 8660683 = 8660688
7 + 8660681 = 8660688
17 + 8660671 = 8660688
31 + 8660657 = 8660688
79 + 8660609 = 8660688
109 + 8660579 = 8660688
149 + 8660539 = 8660688
151 + 8660537 = 8660688

Showing the first eight; more decompositions exist.
