Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512034, here are decompositions:

11 + 31512023 = 31512034
17 + 31512017 = 31512034
23 + 31512011 = 31512034
41 + 31511993 = 31512034
53 + 31511981 = 31512034
101 + 31511933 = 31512034
107 + 31511927 = 31512034
167 + 31511867 = 31512034

Showing the first eight; more decompositions exist.
