Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80912, here are decompositions:

3 + 80909 = 80912
79 + 80833 = 80912
103 + 80809 = 80912
109 + 80803 = 80912
151 + 80761 = 80912
163 + 80749 = 80912
199 + 80713 = 80912
211 + 80701 = 80912

Showing the first eight; more decompositions exist.
