Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622644, here are decompositions:

3 + 31622641 = 31622644
107 + 31622537 = 31622644
461 + 31622183 = 31622644
491 + 31622153 = 31622644
503 + 31622141 = 31622644
563 + 31622081 = 31622644
743 + 31621901 = 31622644
797 + 31621847 = 31622644

Showing the first eight; more decompositions exist.
