Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536304, here are decompositions:

11 + 31536293 = 31536304
17 + 31536287 = 31536304
101 + 31536203 = 31536304
251 + 31536053 = 31536304
557 + 31535747 = 31536304
563 + 31535741 = 31536304
587 + 31535717 = 31536304
647 + 31535657 = 31536304

Showing the first eight; more decompositions exist.
