Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622386, here are decompositions:

17 + 31622369 = 31622386
113 + 31622273 = 31622386
149 + 31622237 = 31622386
179 + 31622207 = 31622386
197 + 31622189 = 31622386
233 + 31622153 = 31622386
239 + 31622147 = 31622386
647 + 31621739 = 31622386

Showing the first eight; more decompositions exist.
