Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622106, here are decompositions:

59 + 31622047 = 31622106
127 + 31621979 = 31622106
149 + 31621957 = 31622106
157 + 31621949 = 31622106
227 + 31621879 = 31622106
353 + 31621753 = 31622106
367 + 31621739 = 31622106
433 + 31621673 = 31622106

Showing the first eight; more decompositions exist.
