Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590684, here are decompositions:

17 + 31590667 = 31590684
53 + 31590631 = 31590684
67 + 31590617 = 31590684
101 + 31590583 = 31590684
113 + 31590571 = 31590684
127 + 31590557 = 31590684
197 + 31590487 = 31590684
233 + 31590451 = 31590684

Showing the first eight; more decompositions exist.
