Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601242, here are decompositions:

191 + 31601051 = 31601242
359 + 31600883 = 31601242
383 + 31600859 = 31601242
419 + 31600823 = 31601242
443 + 31600799 = 31601242
509 + 31600733 = 31601242
521 + 31600721 = 31601242
719 + 31600523 = 31601242

Showing the first eight; more decompositions exist.
