Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514984, here are decompositions:

3 + 31514981 = 31514984
37 + 31514947 = 31514984
73 + 31514911 = 31514984
313 + 31514671 = 31514984
331 + 31514653 = 31514984
433 + 31514551 = 31514984
883 + 31514101 = 31514984
997 + 31513987 = 31514984

Showing the first eight; more decompositions exist.
