Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15966, here are decompositions:

7 + 15959 = 15966
29 + 15937 = 15966
43 + 15923 = 15966
47 + 15919 = 15966
53 + 15913 = 15966
59 + 15907 = 15966
79 + 15887 = 15966
89 + 15877 = 15966

Showing the first eight; more decompositions exist.
