Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600160, here are decompositions:

3 + 31600157 = 31600160
43 + 31600117 = 31600160
61 + 31600099 = 31600160
73 + 31600087 = 31600160
103 + 31600057 = 31600160
283 + 31599877 = 31600160
337 + 31599823 = 31600160
349 + 31599811 = 31600160

Showing the first eight; more decompositions exist.
