Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600888, here are decompositions:

5 + 31600883 = 31600888
29 + 31600859 = 31600888
71 + 31600817 = 31600888
89 + 31600799 = 31600888
167 + 31600721 = 31600888
269 + 31600619 = 31600888
359 + 31600529 = 31600888
467 + 31600421 = 31600888

Showing the first eight; more decompositions exist.
