Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622146, here are decompositions:

5 + 31622141 = 31622146
167 + 31621979 = 31622146
197 + 31621949 = 31622146
443 + 31621703 = 31622146
467 + 31621679 = 31622146
509 + 31621637 = 31622146
587 + 31621559 = 31622146
659 + 31621487 = 31622146

Showing the first eight; more decompositions exist.
