Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30666, here are decompositions:

5 + 30661 = 30666
17 + 30649 = 30666
23 + 30643 = 30666
29 + 30637 = 30666
73 + 30593 = 30666
89 + 30577 = 30666
107 + 30559 = 30666
109 + 30557 = 30666

Showing the first eight; more decompositions exist.
