Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536928, here are decompositions:

11 + 31536917 = 31536928
107 + 31536821 = 31536928
197 + 31536731 = 31536928
389 + 31536539 = 31536928
569 + 31536359 = 31536928
641 + 31536287 = 31536928
701 + 31536227 = 31536928
827 + 31536101 = 31536928

Showing the first eight; more decompositions exist.
