Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527512, here are decompositions:

13 + 31527499 = 31527512
31 + 31527481 = 31527512
571 + 31526941 = 31527512
613 + 31526899 = 31527512
619 + 31526893 = 31527512
631 + 31526881 = 31527512
739 + 31526773 = 31527512
823 + 31526689 = 31527512

Showing the first eight; more decompositions exist.
