Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575266, here are decompositions:

103 + 31575163 = 31575266
127 + 31575139 = 31575266
193 + 31575073 = 31575266
277 + 31574989 = 31575266
379 + 31574887 = 31575266
487 + 31574779 = 31575266
577 + 31574689 = 31575266
769 + 31574497 = 31575266

Showing the first eight; more decompositions exist.
