Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15968, here are decompositions:

31 + 15937 = 15968
61 + 15907 = 15968
67 + 15901 = 15968
79 + 15889 = 15968
109 + 15859 = 15968
151 + 15817 = 15968
181 + 15787 = 15968
229 + 15739 = 15968

Showing the first eight; more decompositions exist.
