Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622054, here are decompositions:

7 + 31622047 = 31622054
73 + 31621981 = 31622054
97 + 31621957 = 31622054
157 + 31621897 = 31622054
223 + 31621831 = 31622054
421 + 31621633 = 31622054
433 + 31621621 = 31622054
463 + 31621591 = 31622054

Showing the first eight; more decompositions exist.
