Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600340, here are decompositions:

7 + 31600333 = 31600340
61 + 31600279 = 31600340
67 + 31600273 = 31600340
139 + 31600201 = 31600340
151 + 31600189 = 31600340
223 + 31600117 = 31600340
241 + 31600099 = 31600340
283 + 31600057 = 31600340

Showing the first eight; more decompositions exist.
