Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560996, here are decompositions:

13 + 31560983 = 31560996
17 + 31560979 = 31560996
53 + 31560943 = 31560996
109 + 31560887 = 31560996
127 + 31560869 = 31560996
149 + 31560847 = 31560996
197 + 31560799 = 31560996
199 + 31560797 = 31560996

Showing the first eight; more decompositions exist.
