Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566794, here are decompositions:

31 + 31566763 = 31566794
163 + 31566631 = 31566794
271 + 31566523 = 31566794
277 + 31566517 = 31566794
307 + 31566487 = 31566794
313 + 31566481 = 31566794
367 + 31566427 = 31566794
397 + 31566397 = 31566794

Showing the first eight; more decompositions exist.
