Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514396, here are decompositions:

157 + 31514239 = 31514396
283 + 31514113 = 31514396
337 + 31514059 = 31514396
373 + 31514023 = 31514396
409 + 31513987 = 31514396
439 + 31513957 = 31514396
523 + 31513873 = 31514396
547 + 31513849 = 31514396

Showing the first eight; more decompositions exist.
