Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544314, here are decompositions:

3 + 31544311 = 31544314
17 + 31544297 = 31544314
101 + 31544213 = 31544314
107 + 31544207 = 31544314
257 + 31544057 = 31544314
281 + 31544033 = 31544314
293 + 31544021 = 31544314
317 + 31543997 = 31544314

Showing the first eight; more decompositions exist.
