Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156996, here are decompositions:

17 + 156979 = 156996
29 + 156967 = 156996
53 + 156943 = 156996
83 + 156913 = 156996
97 + 156899 = 156996
109 + 156887 = 156996
163 + 156833 = 156996
173 + 156823 = 156996

Showing the first eight; more decompositions exist.
