Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566764, here are decompositions:

223 + 31566541 = 31566764
241 + 31566523 = 31566764
277 + 31566487 = 31566764
283 + 31566481 = 31566764
337 + 31566427 = 31566764
367 + 31566397 = 31566764
613 + 31566151 = 31566764
751 + 31566013 = 31566764

Showing the first eight; more decompositions exist.
