Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522716, here are decompositions:

23 + 31522693 = 31522716
47 + 31522669 = 31522716
53 + 31522663 = 31522716
59 + 31522657 = 31522716
83 + 31522633 = 31522716
103 + 31522613 = 31522716
163 + 31522553 = 31522716
167 + 31522549 = 31522716

Showing the first eight; more decompositions exist.
