Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600948, here are decompositions:

89 + 31600859 = 31600948
131 + 31600817 = 31600948
149 + 31600799 = 31600948
227 + 31600721 = 31600948
419 + 31600529 = 31600948
641 + 31600307 = 31600948
647 + 31600301 = 31600948
887 + 31600061 = 31600948

Showing the first eight; more decompositions exist.
