Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83240, here are decompositions:

7 + 83233 = 83240
13 + 83227 = 83240
19 + 83221 = 83240
37 + 83203 = 83240
103 + 83137 = 83240
139 + 83101 = 83240
151 + 83089 = 83240
163 + 83077 = 83240

Showing the first eight; more decompositions exist.
