Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532866, here are decompositions:

3 + 31532863 = 31532866
89 + 31532777 = 31532866
173 + 31532693 = 31532866
179 + 31532687 = 31532866
227 + 31532639 = 31532866
269 + 31532597 = 31532866
293 + 31532573 = 31532866
359 + 31532507 = 31532866

Showing the first eight; more decompositions exist.
