Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83406, here are decompositions:

5 + 83401 = 83406
7 + 83399 = 83406
17 + 83389 = 83406
23 + 83383 = 83406
67 + 83339 = 83406
107 + 83299 = 83406
137 + 83269 = 83406
139 + 83267 = 83406

Showing the first eight; more decompositions exist.
