Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590594, here are decompositions:

5 + 31590589 = 31590594
11 + 31590583 = 31590594
23 + 31590571 = 31590594
37 + 31590557 = 31590594
43 + 31590551 = 31590594
107 + 31590487 = 31590594
127 + 31590467 = 31590594
131 + 31590463 = 31590594

Showing the first eight; more decompositions exist.
