Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30966, here are decompositions:

17 + 30949 = 30966
29 + 30937 = 30966
73 + 30893 = 30966
97 + 30869 = 30966
107 + 30859 = 30966
113 + 30853 = 30966
127 + 30839 = 30966
137 + 30829 = 30966

Showing the first eight; more decompositions exist.
