Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559266, here are decompositions:

3 + 31559263 = 31559266
47 + 31559219 = 31559266
59 + 31559207 = 31559266
173 + 31559093 = 31559266
197 + 31559069 = 31559266
239 + 31559027 = 31559266
269 + 31558997 = 31559266
293 + 31558973 = 31559266

Showing the first eight; more decompositions exist.
