Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619756, here are decompositions:

37 + 8619719 = 8619756
43 + 8619713 = 8619756
73 + 8619683 = 8619756
107 + 8619649 = 8619756
163 + 8619593 = 8619756
283 + 8619473 = 8619756
317 + 8619439 = 8619756
359 + 8619397 = 8619756

Showing the first eight; more decompositions exist.
