Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574744, here are decompositions:

43 + 31574701 = 31574744
67 + 31574677 = 31574744
73 + 31574671 = 31574744
181 + 31574563 = 31574744
277 + 31574467 = 31574744
307 + 31574437 = 31574744
541 + 31574203 = 31574744
571 + 31574173 = 31574744

Showing the first eight; more decompositions exist.
