Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590574, here are decompositions:

3 + 31590571 = 31590574
17 + 31590557 = 31590574
23 + 31590551 = 31590574
107 + 31590467 = 31590574
131 + 31590443 = 31590574
173 + 31590401 = 31590574
311 + 31590263 = 31590574
503 + 31590071 = 31590574

Showing the first eight; more decompositions exist.
