Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600374, here are decompositions:

17 + 31600357 = 31600374
41 + 31600333 = 31600374
67 + 31600307 = 31600374
73 + 31600301 = 31600374
83 + 31600291 = 31600374
97 + 31600277 = 31600374
101 + 31600273 = 31600374
173 + 31600201 = 31600374

Showing the first eight; more decompositions exist.
