Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626594, here are decompositions:

5 + 31626589 = 31626594
23 + 31626571 = 31626594
31 + 31626563 = 31626594
37 + 31626557 = 31626594
47 + 31626547 = 31626594
61 + 31626533 = 31626594
101 + 31626493 = 31626594
113 + 31626481 = 31626594

Showing the first eight; more decompositions exist.
