Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574756, here are decompositions:

67 + 31574689 = 31574756
79 + 31574677 = 31574756
193 + 31574563 = 31574756
277 + 31574479 = 31574756
307 + 31574449 = 31574756
313 + 31574443 = 31574756
337 + 31574419 = 31574756
523 + 31574233 = 31574756

Showing the first eight; more decompositions exist.
