Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522686, here are decompositions:

17 + 31522669 = 31522686
23 + 31522663 = 31522686
29 + 31522657 = 31522686
53 + 31522633 = 31522686
73 + 31522613 = 31522686
89 + 31522597 = 31522686
103 + 31522583 = 31522686
137 + 31522549 = 31522686

Showing the first eight; more decompositions exist.
