Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83378, here are decompositions:

37 + 83341 = 83378
67 + 83311 = 83378
79 + 83299 = 83378
109 + 83269 = 83378
151 + 83227 = 83378
157 + 83221 = 83378
241 + 83137 = 83378
277 + 83101 = 83378

Showing the first eight; more decompositions exist.
