Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622474, here are decompositions:

7 + 31622467 = 31622474
97 + 31622377 = 31622474
127 + 31622347 = 31622474
181 + 31622293 = 31622474
193 + 31622281 = 31622474
307 + 31622167 = 31622474
577 + 31621897 = 31622474
643 + 31621831 = 31622474

Showing the first eight; more decompositions exist.
