Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622828, here are decompositions:

19 + 31622809 = 31622828
157 + 31622671 = 31622828
199 + 31622629 = 31622828
229 + 31622599 = 31622828
337 + 31622491 = 31622828
439 + 31622389 = 31622828
541 + 31622287 = 31622828
547 + 31622281 = 31622828

Showing the first eight; more decompositions exist.
