Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600370, here are decompositions:

13 + 31600357 = 31600370
37 + 31600333 = 31600370
79 + 31600291 = 31600370
97 + 31600273 = 31600370
181 + 31600189 = 31600370
271 + 31600099 = 31600370
283 + 31600087 = 31600370
313 + 31600057 = 31600370

Showing the first eight; more decompositions exist.
