Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631576, here are decompositions:

7 + 8631569 = 8631576
43 + 8631533 = 8631576
59 + 8631517 = 8631576
97 + 8631479 = 8631576
197 + 8631379 = 8631576
257 + 8631319 = 8631576
269 + 8631307 = 8631576
293 + 8631283 = 8631576

Showing the first eight; more decompositions exist.
