Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80340, here are decompositions:

11 + 80329 = 80340
23 + 80317 = 80340
31 + 80309 = 80340
53 + 80287 = 80340
61 + 80279 = 80340
67 + 80273 = 80340
89 + 80251 = 80340
101 + 80239 = 80340

Showing the first eight; more decompositions exist.
