Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512076, here are decompositions:

5 + 31512071 = 31512076
17 + 31512059 = 31512076
53 + 31512023 = 31512076
59 + 31512017 = 31512076
83 + 31511993 = 31512076
107 + 31511969 = 31512076
137 + 31511939 = 31512076
149 + 31511927 = 31512076

Showing the first eight; more decompositions exist.
