Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619646, here are decompositions:

23 + 8619623 = 8619646
53 + 8619593 = 8619646
59 + 8619587 = 8619646
107 + 8619539 = 8619646
137 + 8619509 = 8619646
173 + 8619473 = 8619646
293 + 8619353 = 8619646
383 + 8619263 = 8619646

Showing the first eight; more decompositions exist.
