Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80816, here are decompositions:

7 + 80809 = 80816
13 + 80803 = 80816
37 + 80779 = 80816
67 + 80749 = 80816
79 + 80737 = 80816
103 + 80713 = 80816
139 + 80677 = 80816
367 + 80449 = 80816

Showing the first eight; more decompositions exist.
