Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574724, here are decompositions:

23 + 31574701 = 31574724
31 + 31574693 = 31574724
37 + 31574687 = 31574724
43 + 31574681 = 31574724
47 + 31574677 = 31574724
53 + 31574671 = 31574724
67 + 31574657 = 31574724
193 + 31574531 = 31574724

Showing the first eight; more decompositions exist.
