Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712490, here are decompositions:

167 + 8712323 = 8712490
179 + 8712311 = 8712490
197 + 8712293 = 8712490
233 + 8712257 = 8712490
257 + 8712233 = 8712490
263 + 8712227 = 8712490
317 + 8712173 = 8712490
431 + 8712059 = 8712490

Showing the first eight; more decompositions exist.
