Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574510, here are decompositions:

3 + 31574507 = 31574510
13 + 31574497 = 31574510
31 + 31574479 = 31574510
43 + 31574467 = 31574510
61 + 31574449 = 31574510
67 + 31574443 = 31574510
73 + 31574437 = 31574510
181 + 31574329 = 31574510

Showing the first eight; more decompositions exist.
