Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726320, here are decompositions:

47 + 8726273 = 8726320
179 + 8726141 = 8726320
227 + 8726093 = 8726320
233 + 8726087 = 8726320
257 + 8726063 = 8726320
269 + 8726051 = 8726320
293 + 8726027 = 8726320
359 + 8725961 = 8726320

Showing the first eight; more decompositions exist.
