Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575674, here are decompositions:

3 + 31575671 = 31575674
7 + 31575667 = 31575674
37 + 31575637 = 31575674
103 + 31575571 = 31575674
241 + 31575433 = 31575674
313 + 31575361 = 31575674
337 + 31575337 = 31575674
373 + 31575301 = 31575674

Showing the first eight; more decompositions exist.
