Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42968, here are decompositions:

7 + 42961 = 42968
31 + 42937 = 42968
67 + 42901 = 42968
109 + 42859 = 42968
127 + 42841 = 42968
139 + 42829 = 42968
181 + 42787 = 42968
241 + 42727 = 42968

Showing the first eight; more decompositions exist.
