Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726212, here are decompositions:

3 + 8726209 = 8726212
71 + 8726141 = 8726212
149 + 8726063 = 8726212
191 + 8726021 = 8726212
233 + 8725979 = 8726212
251 + 8725961 = 8726212
263 + 8725949 = 8726212
281 + 8725931 = 8726212

Showing the first eight; more decompositions exist.
