Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590588, here are decompositions:

5 + 31590583 = 31590588
17 + 31590571 = 31590588
31 + 31590557 = 31590588
37 + 31590551 = 31590588
89 + 31590499 = 31590588
101 + 31590487 = 31590588
109 + 31590479 = 31590588
137 + 31590451 = 31590588

Showing the first eight; more decompositions exist.
