Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512484, here are decompositions:

5 + 31512479 = 31512484
137 + 31512347 = 31512484
293 + 31512191 = 31512484
401 + 31512083 = 31512484
461 + 31512023 = 31512484
467 + 31512017 = 31512484
491 + 31511993 = 31512484
503 + 31511981 = 31512484

Showing the first eight; more decompositions exist.
