Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600236, here are decompositions:

43 + 31600193 = 31600236
47 + 31600189 = 31600236
79 + 31600157 = 31600236
103 + 31600133 = 31600236
137 + 31600099 = 31600236
149 + 31600087 = 31600236
179 + 31600057 = 31600236
193 + 31600043 = 31600236

Showing the first eight; more decompositions exist.
