Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622308, here are decompositions:

71 + 31622237 = 31622308
101 + 31622207 = 31622308
167 + 31622141 = 31622308
227 + 31622081 = 31622308
359 + 31621949 = 31622308
461 + 31621847 = 31622308
569 + 31621739 = 31622308
647 + 31621661 = 31622308

Showing the first eight; more decompositions exist.
