Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622926, here are decompositions:

3 + 31622923 = 31622926
89 + 31622837 = 31622926
149 + 31622777 = 31622926
197 + 31622729 = 31622926
227 + 31622699 = 31622926
233 + 31622693 = 31622926
239 + 31622687 = 31622926
263 + 31622663 = 31622926

Showing the first eight; more decompositions exist.
