Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574966, here are decompositions:

79 + 31574887 = 31574966
103 + 31574863 = 31574966
193 + 31574773 = 31574966
277 + 31574689 = 31574966
487 + 31574479 = 31574966
499 + 31574467 = 31574966
523 + 31574443 = 31574966
547 + 31574419 = 31574966

Showing the first eight; more decompositions exist.
