Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522570, here are decompositions:

17 + 31522553 = 31522570
29 + 31522541 = 31522570
41 + 31522529 = 31522570
47 + 31522523 = 31522570
137 + 31522433 = 31522570
197 + 31522373 = 31522570
239 + 31522331 = 31522570
257 + 31522313 = 31522570

Showing the first eight; more decompositions exist.
