Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575062, here are decompositions:

3 + 31575059 = 31575062
73 + 31574989 = 31575062
151 + 31574911 = 31575062
199 + 31574863 = 31575062
241 + 31574821 = 31575062
283 + 31574779 = 31575062
373 + 31574689 = 31575062
499 + 31574563 = 31575062

Showing the first eight; more decompositions exist.
