Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631508, here are decompositions:

29 + 8631479 = 8631508
107 + 8631401 = 8631508
167 + 8631341 = 8631508
239 + 8631269 = 8631508
257 + 8631251 = 8631508
317 + 8631191 = 8631508
467 + 8631041 = 8631508
491 + 8631017 = 8631508

Showing the first eight; more decompositions exist.
