Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693646, here are decompositions:

7 + 8693639 = 8693646
19 + 8693627 = 8693646
23 + 8693623 = 8693646
29 + 8693617 = 8693646
79 + 8693567 = 8693646
97 + 8693549 = 8693646
179 + 8693467 = 8693646
239 + 8693407 = 8693646

Showing the first eight; more decompositions exist.
