Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601404, here are decompositions:

11 + 31601393 = 31601404
47 + 31601357 = 31601404
137 + 31601267 = 31601404
353 + 31601051 = 31601404
521 + 31600883 = 31601404
587 + 31600817 = 31601404
683 + 31600721 = 31601404
701 + 31600703 = 31601404

Showing the first eight; more decompositions exist.
