Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590664, here are decompositions:

5 + 31590659 = 31590664
47 + 31590617 = 31590664
71 + 31590593 = 31590664
107 + 31590557 = 31590664
113 + 31590551 = 31590664
197 + 31590467 = 31590664
251 + 31590413 = 31590664
263 + 31590401 = 31590664

Showing the first eight; more decompositions exist.
