Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600200, here are decompositions:

7 + 31600193 = 31600200
11 + 31600189 = 31600200
43 + 31600157 = 31600200
67 + 31600133 = 31600200
83 + 31600117 = 31600200
97 + 31600103 = 31600200
101 + 31600099 = 31600200
113 + 31600087 = 31600200

Showing the first eight; more decompositions exist.
