Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566264, here are decompositions:

13 + 31566251 = 31566264
17 + 31566247 = 31566264
43 + 31566221 = 31566264
73 + 31566191 = 31566264
97 + 31566167 = 31566264
113 + 31566151 = 31566264
127 + 31566137 = 31566264
181 + 31566083 = 31566264

Showing the first eight; more decompositions exist.
