Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566274, here are decompositions:

23 + 31566251 = 31566274
53 + 31566221 = 31566274
83 + 31566191 = 31566274
107 + 31566167 = 31566274
137 + 31566137 = 31566274
191 + 31566083 = 31566274
197 + 31566077 = 31566274
281 + 31565993 = 31566274

Showing the first eight; more decompositions exist.
