Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30864, here are decompositions:

5 + 30859 = 30864
11 + 30853 = 30864
13 + 30851 = 30864
23 + 30841 = 30864
47 + 30817 = 30864
61 + 30803 = 30864
83 + 30781 = 30864
101 + 30763 = 30864

Showing the first eight; more decompositions exist.
