Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622086, here are decompositions:

5 + 31622081 = 31622086
107 + 31621979 = 31622086
137 + 31621949 = 31622086
239 + 31621847 = 31622086
347 + 31621739 = 31622086
383 + 31621703 = 31622086
449 + 31621637 = 31622086
569 + 31621517 = 31622086

Showing the first eight; more decompositions exist.
