Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626226, here are decompositions:

17 + 31626209 = 31626226
29 + 31626197 = 31626226
59 + 31626167 = 31626226
173 + 31626053 = 31626226
239 + 31625987 = 31626226
257 + 31625969 = 31626226
263 + 31625963 = 31626226
383 + 31625843 = 31626226

Showing the first eight; more decompositions exist.
