Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601134, here are decompositions:

83 + 31601051 = 31601134
251 + 31600883 = 31601134
311 + 31600823 = 31601134
317 + 31600817 = 31601134
401 + 31600733 = 31601134
431 + 31600703 = 31601134
641 + 31600493 = 31601134
683 + 31600451 = 31601134

Showing the first eight; more decompositions exist.
