Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596494, here are decompositions:

103 + 31596391 = 31596494
331 + 31596163 = 31596494
367 + 31596127 = 31596494
373 + 31596121 = 31596494
487 + 31596007 = 31596494
613 + 31595881 = 31596494
661 + 31595833 = 31596494
823 + 31595671 = 31596494

Showing the first eight; more decompositions exist.
