Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600170, here are decompositions:

13 + 31600157 = 31600170
37 + 31600133 = 31600170
53 + 31600117 = 31600170
67 + 31600103 = 31600170
71 + 31600099 = 31600170
83 + 31600087 = 31600170
109 + 31600061 = 31600170
113 + 31600057 = 31600170

Showing the first eight; more decompositions exist.
