Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597612, here are decompositions:

41 + 31597571 = 31597612
71 + 31597541 = 31597612
359 + 31597253 = 31597612
461 + 31597151 = 31597612
491 + 31597121 = 31597612
569 + 31597043 = 31597612
773 + 31596839 = 31597612
863 + 31596749 = 31597612

Showing the first eight; more decompositions exist.
