Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574708, here are decompositions:

7 + 31574701 = 31574708
19 + 31574689 = 31574708
31 + 31574677 = 31574708
37 + 31574671 = 31574708
211 + 31574497 = 31574708
229 + 31574479 = 31574708
241 + 31574467 = 31574708
271 + 31574437 = 31574708

Showing the first eight; more decompositions exist.
