Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622138, here are decompositions:

7 + 31622131 = 31622138
19 + 31622119 = 31622138
157 + 31621981 = 31622138
181 + 31621957 = 31622138
241 + 31621897 = 31622138
307 + 31621831 = 31622138
487 + 31621651 = 31622138
547 + 31621591 = 31622138

Showing the first eight; more decompositions exist.
