Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622524, here are decompositions:

5 + 31622519 = 31622524
251 + 31622273 = 31622524
317 + 31622207 = 31622524
383 + 31622141 = 31622524
443 + 31622081 = 31622524
677 + 31621847 = 31622524
821 + 31621703 = 31622524
863 + 31621661 = 31622524

Showing the first eight; more decompositions exist.
