Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931968, here are decompositions:

19 + 931949 = 931968
47 + 931921 = 931968
61 + 931907 = 931968
67 + 931901 = 931968
109 + 931859 = 931968
131 + 931837 = 931968
157 + 931811 = 931968
179 + 931789 = 931968

Showing the first eight; more decompositions exist.
