Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622044, here are decompositions:

197 + 31621847 = 31622044
383 + 31621661 = 31622044
431 + 31621613 = 31622044
557 + 31621487 = 31622044
617 + 31621427 = 31622044
677 + 31621367 = 31622044
827 + 31621217 = 31622044
887 + 31621157 = 31622044

Showing the first eight; more decompositions exist.
