Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601266, here are decompositions:

3 + 31601263 = 31601266
167 + 31601099 = 31601266
383 + 31600883 = 31601266
443 + 31600823 = 31601266
449 + 31600817 = 31601266
467 + 31600799 = 31601266
563 + 31600703 = 31601266
647 + 31600619 = 31601266

Showing the first eight; more decompositions exist.
