Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522792, here are decompositions:

179 + 31522613 = 31522792
239 + 31522553 = 31522792
251 + 31522541 = 31522792
263 + 31522529 = 31522792
269 + 31522523 = 31522792
359 + 31522433 = 31522792
419 + 31522373 = 31522792
461 + 31522331 = 31522792

Showing the first eight; more decompositions exist.
