Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30768, here are decompositions:

5 + 30763 = 30768
11 + 30757 = 30768
41 + 30727 = 30768
61 + 30707 = 30768
71 + 30697 = 30768
79 + 30689 = 30768
97 + 30671 = 30768
107 + 30661 = 30768

Showing the first eight; more decompositions exist.
