Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590654, here are decompositions:

5 + 31590649 = 31590654
23 + 31590631 = 31590654
37 + 31590617 = 31590654
61 + 31590593 = 31590654
71 + 31590583 = 31590654
83 + 31590571 = 31590654
97 + 31590557 = 31590654
103 + 31590551 = 31590654

Showing the first eight; more decompositions exist.
