Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622182, here are decompositions:

3 + 31622179 = 31622182
29 + 31622153 = 31622182
41 + 31622141 = 31622182
101 + 31622081 = 31622182
233 + 31621949 = 31622182
281 + 31621901 = 31622182
443 + 31621739 = 31622182
479 + 31621703 = 31622182

Showing the first eight; more decompositions exist.
