Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84080, here are decompositions:

13 + 84067 = 84080
19 + 84061 = 84080
97 + 83983 = 84080
211 + 83869 = 84080
223 + 83857 = 84080
307 + 83773 = 84080
379 + 83701 = 84080
439 + 83641 = 84080

Showing the first eight; more decompositions exist.
