Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619790, here are decompositions:

17 + 8619773 = 8619790
71 + 8619719 = 8619790
107 + 8619683 = 8619790
167 + 8619623 = 8619790
197 + 8619593 = 8619790
239 + 8619551 = 8619790
251 + 8619539 = 8619790
281 + 8619509 = 8619790

Showing the first eight; more decompositions exist.
