Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512056, here are decompositions:

19 + 31512037 = 31512056
139 + 31511917 = 31512056
283 + 31511773 = 31512056
313 + 31511743 = 31512056
379 + 31511677 = 31512056
487 + 31511569 = 31512056
523 + 31511533 = 31512056
619 + 31511437 = 31512056

Showing the first eight; more decompositions exist.
