Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601386, here are decompositions:

29 + 31601357 = 31601386
503 + 31600883 = 31601386
563 + 31600823 = 31601386
569 + 31600817 = 31601386
587 + 31600799 = 31601386
653 + 31600733 = 31601386
683 + 31600703 = 31601386
857 + 31600529 = 31601386

Showing the first eight; more decompositions exist.
