Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600984, here are decompositions:

101 + 31600883 = 31600984
167 + 31600817 = 31600984
251 + 31600733 = 31600984
263 + 31600721 = 31600984
281 + 31600703 = 31600984
461 + 31600523 = 31600984
491 + 31600493 = 31600984
563 + 31600421 = 31600984

Showing the first eight; more decompositions exist.
