Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566462, here are decompositions:

13 + 31566449 = 31566462
19 + 31566443 = 31566462
73 + 31566389 = 31566462
79 + 31566383 = 31566462
113 + 31566349 = 31566462
163 + 31566299 = 31566462
173 + 31566289 = 31566462
211 + 31566251 = 31566462

Showing the first eight; more decompositions exist.
