Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544266, here are decompositions:

53 + 31544213 = 31544266
59 + 31544207 = 31544266
113 + 31544153 = 31544266
167 + 31544099 = 31544266
227 + 31544039 = 31544266
233 + 31544033 = 31544266
269 + 31543997 = 31544266
353 + 31543913 = 31544266

Showing the first eight; more decompositions exist.
