Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726278, here are decompositions:

5 + 8726273 = 8726278
137 + 8726141 = 8726278
191 + 8726087 = 8726278
227 + 8726051 = 8726278
251 + 8726027 = 8726278
257 + 8726021 = 8726278
317 + 8725961 = 8726278
347 + 8725931 = 8726278

Showing the first eight; more decompositions exist.
