Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600994, here are decompositions:

37 + 31600957 = 31600994
151 + 31600843 = 31600994
193 + 31600801 = 31600994
211 + 31600783 = 31600994
223 + 31600771 = 31600994
241 + 31600753 = 31600994
277 + 31600717 = 31600994
331 + 31600663 = 31600994

Showing the first eight; more decompositions exist.
