Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575056, here are decompositions:

67 + 31574989 = 31575056
193 + 31574863 = 31575056
277 + 31574779 = 31575056
283 + 31574773 = 31575056
367 + 31574689 = 31575056
379 + 31574677 = 31575056
577 + 31574479 = 31575056
607 + 31574449 = 31575056

Showing the first eight; more decompositions exist.
