Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575584, here are decompositions:

13 + 31575571 = 31575584
31 + 31575553 = 31575584
97 + 31575487 = 31575584
151 + 31575433 = 31575584
223 + 31575361 = 31575584
283 + 31575301 = 31575584
367 + 31575217 = 31575584
421 + 31575163 = 31575584

Showing the first eight; more decompositions exist.
