Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559224, here are decompositions:

5 + 31559219 = 31559224
17 + 31559207 = 31559224
131 + 31559093 = 31559224
173 + 31559051 = 31559224
197 + 31559027 = 31559224
227 + 31558997 = 31559224
251 + 31558973 = 31559224
401 + 31558823 = 31559224

Showing the first eight; more decompositions exist.
