Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608522, here are decompositions:

41 + 31608481 = 31608522
73 + 31608449 = 31608522
173 + 31608349 = 31608522
181 + 31608341 = 31608522
251 + 31608271 = 31608522
353 + 31608169 = 31608522
359 + 31608163 = 31608522
373 + 31608149 = 31608522

Showing the first eight; more decompositions exist.
