Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631486, here are decompositions:

7 + 8631479 = 8631486
107 + 8631379 = 8631486
113 + 8631373 = 8631486
167 + 8631319 = 8631486
179 + 8631307 = 8631486
239 + 8631247 = 8631486
257 + 8631229 = 8631486
293 + 8631193 = 8631486

Showing the first eight; more decompositions exist.
