Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30660, here are decompositions:

11 + 30649 = 30660
17 + 30643 = 30660
23 + 30637 = 30660
29 + 30631 = 30660
67 + 30593 = 30660
83 + 30577 = 30660
101 + 30559 = 30660
103 + 30557 = 30660

Showing the first eight; more decompositions exist.
