Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622584, here are decompositions:

5 + 31622579 = 31622584
47 + 31622537 = 31622584
311 + 31622273 = 31622584
347 + 31622237 = 31622584
401 + 31622183 = 31622584
431 + 31622153 = 31622584
443 + 31622141 = 31622584
503 + 31622081 = 31622584

Showing the first eight; more decompositions exist.
