Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608016, here are decompositions:

3 + 31608013 = 31608016
47 + 31607969 = 31608016
107 + 31607909 = 31608016
113 + 31607903 = 31608016
149 + 31607867 = 31608016
227 + 31607789 = 31608016
233 + 31607783 = 31608016
269 + 31607747 = 31608016

Showing the first eight; more decompositions exist.
