Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30774, here are decompositions:

11 + 30763 = 30774
17 + 30757 = 30774
47 + 30727 = 30774
61 + 30713 = 30774
67 + 30707 = 30774
71 + 30703 = 30774
97 + 30677 = 30774
103 + 30671 = 30774

Showing the first eight; more decompositions exist.
