Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622434, here are decompositions:

5 + 31622429 = 31622434
197 + 31622237 = 31622434
227 + 31622207 = 31622434
251 + 31622183 = 31622434
281 + 31622153 = 31622434
293 + 31622141 = 31622434
353 + 31622081 = 31622434
587 + 31621847 = 31622434

Showing the first eight; more decompositions exist.
