Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622740, here are decompositions:

11 + 31622729 = 31622740
41 + 31622699 = 31622740
47 + 31622693 = 31622740
53 + 31622687 = 31622740
311 + 31622429 = 31622740
467 + 31622273 = 31622740
503 + 31622237 = 31622740
557 + 31622183 = 31622740

Showing the first eight; more decompositions exist.
