Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575716, here are decompositions:

19 + 31575697 = 31575716
79 + 31575637 = 31575716
163 + 31575553 = 31575716
229 + 31575487 = 31575716
283 + 31575433 = 31575716
379 + 31575337 = 31575716
499 + 31575217 = 31575716
577 + 31575139 = 31575716

Showing the first eight; more decompositions exist.
