Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566676, here are decompositions:

17 + 31566659 = 31566676
149 + 31566527 = 31566676
179 + 31566497 = 31566676
227 + 31566449 = 31566676
233 + 31566443 = 31566676
293 + 31566383 = 31566676
347 + 31566329 = 31566676
359 + 31566317 = 31566676

Showing the first eight; more decompositions exist.
