Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609058, here are decompositions:

241 + 31608817 = 31609058
331 + 31608727 = 31609058
337 + 31608721 = 31609058
577 + 31608481 = 31609058
631 + 31608427 = 31609058
709 + 31608349 = 31609058
739 + 31608319 = 31609058
757 + 31608301 = 31609058

Showing the first eight; more decompositions exist.
