Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536916, here are decompositions:

53 + 31536863 = 31536916
197 + 31536719 = 31536916
557 + 31536359 = 31536916
563 + 31536353 = 31536916
569 + 31536347 = 31536916
863 + 31536053 = 31536916
977 + 31535939 = 31536916
1163 + 31535753 = 31536916

Showing the first eight; more decompositions exist.
