Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514282, here are decompositions:

43 + 31514239 = 31514282
61 + 31514221 = 31514282
139 + 31514143 = 31514282
181 + 31514101 = 31514282
223 + 31514059 = 31514282
409 + 31513873 = 31514282
433 + 31513849 = 31514282
439 + 31513843 = 31514282

Showing the first eight; more decompositions exist.
