Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622234, here are decompositions:

67 + 31622167 = 31622234
103 + 31622131 = 31622234
271 + 31621963 = 31622234
277 + 31621957 = 31622234
337 + 31621897 = 31622234
541 + 31621693 = 31622234
601 + 31621633 = 31622234
613 + 31621621 = 31622234

Showing the first eight; more decompositions exist.
