Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567708, here are decompositions:

59 + 31567649 = 31567708
71 + 31567637 = 31567708
89 + 31567619 = 31567708
149 + 31567559 = 31567708
197 + 31567511 = 31567708
257 + 31567451 = 31567708
281 + 31567427 = 31567708
311 + 31567397 = 31567708

Showing the first eight; more decompositions exist.
