Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522810, here are decompositions:

197 + 31522613 = 31522810
227 + 31522583 = 31522810
257 + 31522553 = 31522810
269 + 31522541 = 31522810
281 + 31522529 = 31522810
317 + 31522493 = 31522810
359 + 31522451 = 31522810
479 + 31522331 = 31522810

Showing the first eight; more decompositions exist.
