Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30968, here are decompositions:

19 + 30949 = 30968
31 + 30937 = 30968
37 + 30931 = 30968
97 + 30871 = 30968
109 + 30859 = 30968
127 + 30841 = 30968
139 + 30829 = 30968
151 + 30817 = 30968

Showing the first eight; more decompositions exist.
