Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514352, here are decompositions:

43 + 31514309 = 31514352
61 + 31514291 = 31514352
113 + 31514239 = 31514352
131 + 31514221 = 31514352
193 + 31514159 = 31514352
239 + 31514113 = 31514352
251 + 31514101 = 31514352
271 + 31514081 = 31514352

Showing the first eight; more decompositions exist.
