Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575224, here are decompositions:

3 + 31575221 = 31575224
7 + 31575217 = 31575224
61 + 31575163 = 31575224
73 + 31575151 = 31575224
151 + 31575073 = 31575224
313 + 31574911 = 31575224
337 + 31574887 = 31575224
523 + 31574701 = 31575224

Showing the first eight; more decompositions exist.
