Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522668, here are decompositions:

5 + 31522663 = 31522668
11 + 31522657 = 31522668
71 + 31522597 = 31522668
127 + 31522541 = 31522668
139 + 31522529 = 31522668
227 + 31522441 = 31522668
257 + 31522411 = 31522668
311 + 31522357 = 31522668

Showing the first eight; more decompositions exist.
