Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30824, here are decompositions:

7 + 30817 = 30824
43 + 30781 = 30824
61 + 30763 = 30824
67 + 30757 = 30824
97 + 30727 = 30824
127 + 30697 = 30824
163 + 30661 = 30824
181 + 30643 = 30824

Showing the first eight; more decompositions exist.
