Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522812, here are decompositions:

149 + 31522663 = 31522812
179 + 31522633 = 31522812
199 + 31522613 = 31522812
229 + 31522583 = 31522812
263 + 31522549 = 31522812
271 + 31522541 = 31522812
283 + 31522529 = 31522812
353 + 31522459 = 31522812

Showing the first eight; more decompositions exist.
