Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600298, here are decompositions:

7 + 31600291 = 31600298
19 + 31600279 = 31600298
97 + 31600201 = 31600298
109 + 31600189 = 31600298
181 + 31600117 = 31600298
199 + 31600099 = 31600298
211 + 31600087 = 31600298
241 + 31600057 = 31600298

Showing the first eight; more decompositions exist.
