Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607794, here are decompositions:

3 + 31607791 = 31607794
5 + 31607789 = 31607794
11 + 31607783 = 31607794
47 + 31607747 = 31607794
107 + 31607687 = 31607794
263 + 31607531 = 31607794
347 + 31607447 = 31607794
431 + 31607363 = 31607794

Showing the first eight; more decompositions exist.
