Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600936, here are decompositions:

53 + 31600883 = 31600936
113 + 31600823 = 31600936
137 + 31600799 = 31600936
233 + 31600703 = 31600936
317 + 31600619 = 31600936
443 + 31600493 = 31600936
617 + 31600319 = 31600936
659 + 31600277 = 31600936

Showing the first eight; more decompositions exist.
