Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574968, here are decompositions:

41 + 31574927 = 31574968
107 + 31574861 = 31574968
281 + 31574687 = 31574968
311 + 31574657 = 31574968
461 + 31574507 = 31574968
479 + 31574489 = 31574968
599 + 31574369 = 31574968
641 + 31574327 = 31574968

Showing the first eight; more decompositions exist.
