Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575374, here are decompositions:

13 + 31575361 = 31575374
37 + 31575337 = 31575374
73 + 31575301 = 31575374
157 + 31575217 = 31575374
211 + 31575163 = 31575374
223 + 31575151 = 31575374
283 + 31575091 = 31575374
463 + 31574911 = 31575374

Showing the first eight; more decompositions exist.
