Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600882, here are decompositions:

23 + 31600859 = 31600882
59 + 31600823 = 31600882
83 + 31600799 = 31600882
149 + 31600733 = 31600882
179 + 31600703 = 31600882
263 + 31600619 = 31600882
353 + 31600529 = 31600882
359 + 31600523 = 31600882

Showing the first eight; more decompositions exist.
