Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522996, here are decompositions:

17 + 31522979 = 31522996
59 + 31522937 = 31522996
107 + 31522889 = 31522996
149 + 31522847 = 31522996
173 + 31522823 = 31522996
383 + 31522613 = 31522996
443 + 31522553 = 31522996
467 + 31522529 = 31522996

Showing the first eight; more decompositions exist.
