Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600834, here are decompositions:

11 + 31600823 = 31600834
17 + 31600817 = 31600834
101 + 31600733 = 31600834
113 + 31600721 = 31600834
131 + 31600703 = 31600834
311 + 31600523 = 31600834
383 + 31600451 = 31600834
557 + 31600277 = 31600834

Showing the first eight; more decompositions exist.
