Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726238, here are decompositions:

11 + 8726227 = 8726238
29 + 8726209 = 8726238
41 + 8726197 = 8726238
97 + 8726141 = 8726238
137 + 8726101 = 8726238
151 + 8726087 = 8726238
211 + 8726027 = 8726238
239 + 8725999 = 8726238

Showing the first eight; more decompositions exist.
