Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590908, here are decompositions:

31 + 31590877 = 31590908
61 + 31590847 = 31590908
67 + 31590841 = 31590908
241 + 31590667 = 31590908
277 + 31590631 = 31590908
337 + 31590571 = 31590908
409 + 31590499 = 31590908
421 + 31590487 = 31590908

Showing the first eight; more decompositions exist.
