Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622670, here are decompositions:

7 + 31622663 = 31622670
29 + 31622641 = 31622670
41 + 31622629 = 31622670
71 + 31622599 = 31622670
151 + 31622519 = 31622670
179 + 31622491 = 31622670
197 + 31622473 = 31622670
241 + 31622429 = 31622670

Showing the first eight; more decompositions exist.
