Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508176, here are decompositions:

5 + 31508171 = 31508176
17 + 31508159 = 31508176
23 + 31508153 = 31508176
83 + 31508093 = 31508176
137 + 31508039 = 31508176
149 + 31508027 = 31508176
173 + 31508003 = 31508176
263 + 31507913 = 31508176

Showing the first eight; more decompositions exist.
