Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512014, here are decompositions:

3 + 31512011 = 31512014
97 + 31511917 = 31512014
211 + 31511803 = 31512014
241 + 31511773 = 31512014
271 + 31511743 = 31512014
337 + 31511677 = 31512014
463 + 31511551 = 31512014
487 + 31511527 = 31512014

Showing the first eight; more decompositions exist.
