Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80516, here are decompositions:

3 + 80513 = 80516
43 + 80473 = 80516
67 + 80449 = 80516
109 + 80407 = 80516
199 + 80317 = 80516
229 + 80287 = 80516
277 + 80239 = 80516
283 + 80233 = 80516

Showing the first eight; more decompositions exist.
