Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566776, here are decompositions:

13 + 31566763 = 31566776
67 + 31566709 = 31566776
229 + 31566547 = 31566776
349 + 31566427 = 31566776
379 + 31566397 = 31566776
487 + 31566289 = 31566776
607 + 31566169 = 31566776
733 + 31566043 = 31566776

Showing the first eight; more decompositions exist.
