Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601632, here are decompositions:

3 + 31601629 = 31601632
239 + 31601393 = 31601632
773 + 31600859 = 31601632
809 + 31600823 = 31601632
911 + 31600721 = 31601632
929 + 31600703 = 31601632
1013 + 31600619 = 31601632
1103 + 31600529 = 31601632

Showing the first eight; more decompositions exist.
