Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622806, here are decompositions:

3 + 31622803 = 31622806
29 + 31622777 = 31622806
107 + 31622699 = 31622806
113 + 31622693 = 31622806
227 + 31622579 = 31622806
269 + 31622537 = 31622806
569 + 31622237 = 31622806
599 + 31622207 = 31622806

Showing the first eight; more decompositions exist.
