Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84020, here are decompositions:

3 + 84017 = 84020
37 + 83983 = 84020
109 + 83911 = 84020
151 + 83869 = 84020
163 + 83857 = 84020
229 + 83791 = 84020
283 + 83737 = 84020
331 + 83689 = 84020

Showing the first eight; more decompositions exist.
