Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544272, here are decompositions:

59 + 31544213 = 31544272
83 + 31544189 = 31544272
101 + 31544171 = 31544272
173 + 31544099 = 31544272
233 + 31544039 = 31544272
239 + 31544033 = 31544272
251 + 31544021 = 31544272
281 + 31543991 = 31544272

Showing the first eight; more decompositions exist.
