Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574704, here are decompositions:

3 + 31574701 = 31574704
11 + 31574693 = 31574704
17 + 31574687 = 31574704
23 + 31574681 = 31574704
47 + 31574657 = 31574704
173 + 31574531 = 31574704
197 + 31574507 = 31574704
251 + 31574453 = 31574704

Showing the first eight; more decompositions exist.
