Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508794, here are decompositions:

3 + 31508791 = 31508794
47 + 31508747 = 31508794
113 + 31508681 = 31508794
137 + 31508657 = 31508794
173 + 31508621 = 31508794
227 + 31508567 = 31508794
431 + 31508363 = 31508794
563 + 31508231 = 31508794

Showing the first eight; more decompositions exist.
