Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575704, here are decompositions:

7 + 31575697 = 31575704
37 + 31575667 = 31575704
67 + 31575637 = 31575704
151 + 31575553 = 31575704
271 + 31575433 = 31575704
367 + 31575337 = 31575704
463 + 31575241 = 31575704
487 + 31575217 = 31575704

Showing the first eight; more decompositions exist.
