Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512064, here are decompositions:

5 + 31512059 = 31512064
41 + 31512023 = 31512064
47 + 31512017 = 31512064
53 + 31512011 = 31512064
71 + 31511993 = 31512064
83 + 31511981 = 31512064
131 + 31511933 = 31512064
137 + 31511927 = 31512064

Showing the first eight; more decompositions exist.
