Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622706, here are decompositions:

7 + 31622699 = 31622706
13 + 31622693 = 31622706
19 + 31622687 = 31622706
23 + 31622683 = 31622706
43 + 31622663 = 31622706
107 + 31622599 = 31622706
127 + 31622579 = 31622706
197 + 31622509 = 31622706

Showing the first eight; more decompositions exist.
