Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622116, here are decompositions:

3 + 31622113 = 31622116
137 + 31621979 = 31622116
167 + 31621949 = 31622116
269 + 31621847 = 31622116
443 + 31621673 = 31622116
479 + 31621637 = 31622116
503 + 31621613 = 31622116
557 + 31621559 = 31622116

Showing the first eight; more decompositions exist.
