Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622128, here are decompositions:

47 + 31622081 = 31622128
149 + 31621979 = 31622128
179 + 31621949 = 31622128
227 + 31621901 = 31622128
281 + 31621847 = 31622128
389 + 31621739 = 31622128
449 + 31621679 = 31622128
467 + 31621661 = 31622128

Showing the first eight; more decompositions exist.
