Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619772, here are decompositions:

53 + 8619719 = 8619772
59 + 8619713 = 8619772
89 + 8619683 = 8619772
149 + 8619623 = 8619772
179 + 8619593 = 8619772
233 + 8619539 = 8619772
263 + 8619509 = 8619772
281 + 8619491 = 8619772

Showing the first eight; more decompositions exist.
