Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446224, here are decompositions:

13 + 31446211 = 31446224
127 + 31446097 = 31446224
157 + 31446067 = 31446224
163 + 31446061 = 31446224
193 + 31446031 = 31446224
241 + 31445983 = 31446224
283 + 31445941 = 31446224
307 + 31445917 = 31446224

Showing the first eight; more decompositions exist.
