Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660646, here are decompositions:

23 + 8660623 = 8660646
37 + 8660609 = 8660646
67 + 8660579 = 8660646
103 + 8660543 = 8660646
107 + 8660539 = 8660646
109 + 8660537 = 8660646
139 + 8660507 = 8660646
179 + 8660467 = 8660646

Showing the first eight; more decompositions exist.
