Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512060, here are decompositions:

23 + 31512037 = 31512060
37 + 31512023 = 31512060
43 + 31512017 = 31512060
67 + 31511993 = 31512060
79 + 31511981 = 31512060
127 + 31511933 = 31512060
179 + 31511881 = 31512060
191 + 31511869 = 31512060

Showing the first eight; more decompositions exist.
