Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663646, here are decompositions:

37 + 8663609 = 8663646
53 + 8663593 = 8663646
67 + 8663579 = 8663646
109 + 8663537 = 8663646
127 + 8663519 = 8663646
137 + 8663509 = 8663646
139 + 8663507 = 8663646
149 + 8663497 = 8663646

Showing the first eight; more decompositions exist.
