Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600196, here are decompositions:

3 + 31600193 = 31600196
7 + 31600189 = 31600196
79 + 31600117 = 31600196
97 + 31600099 = 31600196
109 + 31600087 = 31600196
139 + 31600057 = 31600196
157 + 31600039 = 31600196
283 + 31599913 = 31600196

Showing the first eight; more decompositions exist.
