Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508332, here are decompositions:

3 + 31508329 = 31508332
101 + 31508231 = 31508332
173 + 31508159 = 31508332
179 + 31508153 = 31508332
239 + 31508093 = 31508332
293 + 31508039 = 31508332
419 + 31507913 = 31508332
431 + 31507901 = 31508332

Showing the first eight; more decompositions exist.
