Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80966, here are decompositions:

3 + 80963 = 80966
13 + 80953 = 80966
37 + 80929 = 80966
43 + 80923 = 80966
103 + 80863 = 80966
157 + 80809 = 80966
163 + 80803 = 80966
229 + 80737 = 80966

Showing the first eight; more decompositions exist.
