Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600556, here are decompositions:

7 + 31600549 = 31600556
103 + 31600453 = 31600556
109 + 31600447 = 31600556
199 + 31600357 = 31600556
223 + 31600333 = 31600556
277 + 31600279 = 31600556
283 + 31600273 = 31600556
367 + 31600189 = 31600556

Showing the first eight; more decompositions exist.
