Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514402, here are decompositions:

163 + 31514239 = 31514402
181 + 31514221 = 31514402
211 + 31514191 = 31514402
379 + 31514023 = 31514402
523 + 31513879 = 31514402
571 + 31513831 = 31514402
709 + 31513693 = 31514402
823 + 31513579 = 31514402

Showing the first eight; more decompositions exist.
