Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575914, here are decompositions:

37 + 31575877 = 31575914
277 + 31575637 = 31575914
577 + 31575337 = 31575914
613 + 31575301 = 31575914
673 + 31575241 = 31575914
751 + 31575163 = 31575914
823 + 31575091 = 31575914
1051 + 31574863 = 31575914

Showing the first eight; more decompositions exist.
