Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590968, here are decompositions:

37 + 31590931 = 31590968
61 + 31590907 = 31590968
127 + 31590841 = 31590968
229 + 31590739 = 31590968
337 + 31590631 = 31590968
379 + 31590589 = 31590968
397 + 31590571 = 31590968
499 + 31590469 = 31590968

Showing the first eight; more decompositions exist.
