Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590694, here are decompositions:

11 + 31590683 = 31590694
101 + 31590593 = 31590694
137 + 31590557 = 31590694
227 + 31590467 = 31590694
251 + 31590443 = 31590694
281 + 31590413 = 31590694
293 + 31590401 = 31590694
431 + 31590263 = 31590694

Showing the first eight; more decompositions exist.
