Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631618, here are decompositions:

7 + 8631611 = 8631618
19 + 8631599 = 8631618
101 + 8631517 = 8631618
139 + 8631479 = 8631618
167 + 8631451 = 8631618
227 + 8631391 = 8631618
239 + 8631379 = 8631618
251 + 8631367 = 8631618

Showing the first eight; more decompositions exist.
