Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622122, here are decompositions:

3 + 31622119 = 31622122
41 + 31622081 = 31622122
173 + 31621949 = 31622122
383 + 31621739 = 31622122
419 + 31621703 = 31622122
443 + 31621679 = 31622122
449 + 31621673 = 31622122
461 + 31621661 = 31622122

Showing the first eight; more decompositions exist.
