Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536936, here are decompositions:

19 + 31536917 = 31536936
73 + 31536863 = 31536936
89 + 31536847 = 31536936
107 + 31536829 = 31536936
113 + 31536823 = 31536936
163 + 31536773 = 31536936
229 + 31536707 = 31536936
239 + 31536697 = 31536936

Showing the first eight; more decompositions exist.
