Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726218, here are decompositions:

131 + 8726087 = 8726218
167 + 8726051 = 8726218
191 + 8726027 = 8726218
197 + 8726021 = 8726218
227 + 8725991 = 8726218
239 + 8725979 = 8726218
257 + 8725961 = 8726218
269 + 8725949 = 8726218

Showing the first eight; more decompositions exist.
