Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540956, here are decompositions:

17 + 31540939 = 31540956
89 + 31540867 = 31540956
173 + 31540783 = 31540956
229 + 31540727 = 31540956
233 + 31540723 = 31540956
257 + 31540699 = 31540956
263 + 31540693 = 31540956
277 + 31540679 = 31540956

Showing the first eight; more decompositions exist.
