Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574924, here are decompositions:

13 + 31574911 = 31574924
37 + 31574887 = 31574924
61 + 31574863 = 31574924
103 + 31574821 = 31574924
151 + 31574773 = 31574924
223 + 31574701 = 31574924
457 + 31574467 = 31574924
487 + 31574437 = 31574924

Showing the first eight; more decompositions exist.
