Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622866, here are decompositions:

3 + 31622863 = 31622866
29 + 31622837 = 31622866
89 + 31622777 = 31622866
137 + 31622729 = 31622866
167 + 31622699 = 31622866
173 + 31622693 = 31622866
179 + 31622687 = 31622866
347 + 31622519 = 31622866

Showing the first eight; more decompositions exist.
