Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544134, here are decompositions:

3 + 31544131 = 31544134
101 + 31544033 = 31544134
113 + 31544021 = 31544134
137 + 31543997 = 31544134
173 + 31543961 = 31544134
227 + 31543907 = 31544134
257 + 31543877 = 31544134
263 + 31543871 = 31544134

Showing the first eight; more decompositions exist.
