Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536836, here are decompositions:

7 + 31536829 = 31536836
13 + 31536823 = 31536836
43 + 31536793 = 31536836
103 + 31536733 = 31536836
139 + 31536697 = 31536836
223 + 31536613 = 31536836
229 + 31536607 = 31536836
307 + 31536529 = 31536836

Showing the first eight; more decompositions exist.
