Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536716, here are decompositions:

19 + 31536697 = 31536716
103 + 31536613 = 31536716
109 + 31536607 = 31536716
313 + 31536403 = 31536716
619 + 31536097 = 31536716
733 + 31535983 = 31536716
769 + 31535947 = 31536716
907 + 31535809 = 31536716

Showing the first eight; more decompositions exist.
