Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566682, here are decompositions:

23 + 31566659 = 31566682
71 + 31566611 = 31566682
83 + 31566599 = 31566682
233 + 31566449 = 31566682
239 + 31566443 = 31566682
293 + 31566389 = 31566682
353 + 31566329 = 31566682
383 + 31566299 = 31566682

Showing the first eight; more decompositions exist.
