Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156980, here are decompositions:

13 + 156967 = 156980
37 + 156943 = 156980
67 + 156913 = 156980
79 + 156901 = 156980
139 + 156841 = 156980
157 + 156823 = 156980
163 + 156817 = 156980
181 + 156799 = 156980

Showing the first eight; more decompositions exist.
