Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83408, here are decompositions:

7 + 83401 = 83408
19 + 83389 = 83408
67 + 83341 = 83408
97 + 83311 = 83408
109 + 83299 = 83408
139 + 83269 = 83408
151 + 83257 = 83408
181 + 83227 = 83408

Showing the first eight; more decompositions exist.
