Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30680, here are decompositions:

3 + 30677 = 30680
19 + 30661 = 30680
31 + 30649 = 30680
37 + 30643 = 30680
43 + 30637 = 30680
103 + 30577 = 30680
127 + 30553 = 30680
151 + 30529 = 30680

Showing the first eight; more decompositions exist.
