Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663618, here are decompositions:

97 + 8663521 = 8663618
109 + 8663509 = 8663618
151 + 8663467 = 8663618
157 + 8663461 = 8663618
181 + 8663437 = 8663618
307 + 8663311 = 8663618
409 + 8663209 = 8663618
499 + 8663119 = 8663618

Showing the first eight; more decompositions exist.
