Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536164, here are decompositions:

3 + 31536161 = 31536164
67 + 31536097 = 31536164
103 + 31536061 = 31536164
181 + 31535983 = 31536164
223 + 31535941 = 31536164
337 + 31535827 = 31536164
367 + 31535797 = 31536164
571 + 31535593 = 31536164

Showing the first eight; more decompositions exist.
