Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726188, here are decompositions:

47 + 8726141 = 8726188
101 + 8726087 = 8726188
137 + 8726051 = 8726188
167 + 8726021 = 8726188
197 + 8725991 = 8726188
227 + 8725961 = 8726188
239 + 8725949 = 8726188
257 + 8725931 = 8726188

Showing the first eight; more decompositions exist.
