Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600434, here are decompositions:

11 + 31600423 = 31600434
13 + 31600421 = 31600434
101 + 31600333 = 31600434
127 + 31600307 = 31600434
157 + 31600277 = 31600434
233 + 31600201 = 31600434
241 + 31600193 = 31600434
277 + 31600157 = 31600434

Showing the first eight; more decompositions exist.
