Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604824, here are decompositions:

101 + 31604723 = 31604824
137 + 31604687 = 31604824
197 + 31604627 = 31604824
263 + 31604561 = 31604824
467 + 31604357 = 31604824
521 + 31604303 = 31604824
773 + 31604051 = 31604824
947 + 31603877 = 31604824

Showing the first eight; more decompositions exist.
