Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618512, here are decompositions:

11 + 8618501 = 8618512
29 + 8618483 = 8618512
83 + 8618429 = 8618512
173 + 8618339 = 8618512
239 + 8618273 = 8618512
269 + 8618243 = 8618512
449 + 8618063 = 8618512
479 + 8618033 = 8618512

Showing the first eight; more decompositions exist.
