Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539014, here are decompositions:

7 + 31539007 = 31539014
127 + 31538887 = 31539014
271 + 31538743 = 31539014
373 + 31538641 = 31539014
433 + 31538581 = 31539014
457 + 31538557 = 31539014
487 + 31538527 = 31539014
523 + 31538491 = 31539014

Showing the first eight; more decompositions exist.
