Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622246, here are decompositions:

67 + 31622179 = 31622246
79 + 31622167 = 31622246
127 + 31622119 = 31622246
199 + 31622047 = 31622246
283 + 31621963 = 31622246
349 + 31621897 = 31622246
367 + 31621879 = 31622246
577 + 31621669 = 31622246

Showing the first eight; more decompositions exist.
