Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608036, here are decompositions:

7 + 31608029 = 31608036
23 + 31608013 = 31608036
67 + 31607969 = 31608036
127 + 31607909 = 31608036
139 + 31607897 = 31608036
167 + 31607869 = 31608036
179 + 31607857 = 31608036
197 + 31607839 = 31608036

Showing the first eight; more decompositions exist.
