Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574696, here are decompositions:

3 + 31574693 = 31574696
7 + 31574689 = 31574696
19 + 31574677 = 31574696
199 + 31574497 = 31574696
229 + 31574467 = 31574696
277 + 31574419 = 31574696
367 + 31574329 = 31574696
463 + 31574233 = 31574696

Showing the first eight; more decompositions exist.
