Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728246, here are decompositions:

5 + 8728241 = 8728246
53 + 8728193 = 8728246
167 + 8728079 = 8728246
173 + 8728073 = 8728246
257 + 8727989 = 8728246
347 + 8727899 = 8728246
389 + 8727857 = 8728246
467 + 8727779 = 8728246

Showing the first eight; more decompositions exist.
