Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622468, here are decompositions:

79 + 31622389 = 31622468
181 + 31622287 = 31622468
211 + 31622257 = 31622468
337 + 31622131 = 31622468
349 + 31622119 = 31622468
421 + 31622047 = 31622468
487 + 31621981 = 31622468
571 + 31621897 = 31622468

Showing the first eight; more decompositions exist.
