Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522650, here are decompositions:

17 + 31522633 = 31522650
37 + 31522613 = 31522650
53 + 31522597 = 31522650
59 + 31522591 = 31522650
67 + 31522583 = 31522650
97 + 31522553 = 31522650
101 + 31522549 = 31522650
109 + 31522541 = 31522650

Showing the first eight; more decompositions exist.
