Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30668, here are decompositions:

7 + 30661 = 30668
19 + 30649 = 30668
31 + 30637 = 30668
37 + 30631 = 30668
109 + 30559 = 30668
139 + 30529 = 30668
151 + 30517 = 30668
199 + 30469 = 30668

Showing the first eight; more decompositions exist.
