Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514684, here are decompositions:

13 + 31514671 = 31514684
31 + 31514653 = 31514684
43 + 31514641 = 31514684
151 + 31514533 = 31514684
211 + 31514473 = 31514684
283 + 31514401 = 31514684
463 + 31514221 = 31514684
541 + 31514143 = 31514684

Showing the first eight; more decompositions exist.
