Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574852, here are decompositions:

3 + 31574849 = 31574852
31 + 31574821 = 31574852
73 + 31574779 = 31574852
79 + 31574773 = 31574852
151 + 31574701 = 31574852
163 + 31574689 = 31574852
181 + 31574671 = 31574852
373 + 31574479 = 31574852

Showing the first eight; more decompositions exist.
