Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596536, here are decompositions:

157 + 31596379 = 31596536
229 + 31596307 = 31596536
373 + 31596163 = 31596536
409 + 31596127 = 31596536
487 + 31596049 = 31596536
547 + 31595989 = 31596536
607 + 31595929 = 31596536
883 + 31595653 = 31596536

Showing the first eight; more decompositions exist.
