Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622700, here are decompositions:

7 + 31622693 = 31622700
13 + 31622687 = 31622700
17 + 31622683 = 31622700
29 + 31622671 = 31622700
37 + 31622663 = 31622700
59 + 31622641 = 31622700
71 + 31622629 = 31622700
101 + 31622599 = 31622700

Showing the first eight; more decompositions exist.
