Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536966, here are decompositions:

7 + 31536959 = 31536966
23 + 31536943 = 31536966
29 + 31536937 = 31536966
103 + 31536863 = 31536966
137 + 31536829 = 31536966
173 + 31536793 = 31536966
193 + 31536773 = 31536966
233 + 31536733 = 31536966

Showing the first eight; more decompositions exist.
