Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83420, here are decompositions:

3 + 83417 = 83420
13 + 83407 = 83420
19 + 83401 = 83420
31 + 83389 = 83420
37 + 83383 = 83420
79 + 83341 = 83420
109 + 83311 = 83420
151 + 83269 = 83420

Showing the first eight; more decompositions exist.
