Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726284, here are decompositions:

11 + 8726273 = 8726284
41 + 8726243 = 8726284
191 + 8726093 = 8726284
197 + 8726087 = 8726284
233 + 8726051 = 8726284
257 + 8726027 = 8726284
263 + 8726021 = 8726284
293 + 8725991 = 8726284

Showing the first eight; more decompositions exist.
