Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604936, here are decompositions:

3 + 31604933 = 31604936
73 + 31604863 = 31604936
193 + 31604743 = 31604936
379 + 31604557 = 31604936
439 + 31604497 = 31604936
577 + 31604359 = 31604936
673 + 31604263 = 31604936
709 + 31604227 = 31604936

Showing the first eight; more decompositions exist.
