Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622030, here are decompositions:

67 + 31621963 = 31622030
73 + 31621957 = 31622030
151 + 31621879 = 31622030
199 + 31621831 = 31622030
277 + 31621753 = 31622030
337 + 31621693 = 31622030
379 + 31621651 = 31622030
397 + 31621633 = 31622030

Showing the first eight; more decompositions exist.
