Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151968, here are decompositions:

29 + 151939 = 151968
31 + 151937 = 151968
59 + 151909 = 151968
67 + 151901 = 151968
71 + 151897 = 151968
97 + 151871 = 151968
127 + 151841 = 151968
151 + 151817 = 151968

Showing the first eight; more decompositions exist.
