Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619664, here are decompositions:

3 + 8619661 = 8619664
41 + 8619623 = 8619664
71 + 8619593 = 8619664
113 + 8619551 = 8619664
173 + 8619491 = 8619664
191 + 8619473 = 8619664
227 + 8619437 = 8619664
233 + 8619431 = 8619664

Showing the first eight; more decompositions exist.
