Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80828, here are decompositions:

19 + 80809 = 80828
67 + 80761 = 80828
79 + 80749 = 80828
127 + 80701 = 80828
151 + 80677 = 80828
157 + 80671 = 80828
199 + 80629 = 80828
229 + 80599 = 80828

Showing the first eight; more decompositions exist.
