Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622730, here are decompositions:

17 + 31622713 = 31622730
31 + 31622699 = 31622730
37 + 31622693 = 31622730
43 + 31622687 = 31622730
47 + 31622683 = 31622730
59 + 31622671 = 31622730
67 + 31622663 = 31622730
89 + 31622641 = 31622730

Showing the first eight; more decompositions exist.
