Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665624, here are decompositions:

5 + 8665619 = 8665624
41 + 8665583 = 8665624
53 + 8665571 = 8665624
83 + 8665541 = 8665624
173 + 8665451 = 8665624
251 + 8665373 = 8665624
263 + 8665361 = 8665624
311 + 8665313 = 8665624

Showing the first eight; more decompositions exist.
