Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83238, here are decompositions:

5 + 83233 = 83238
7 + 83231 = 83238
11 + 83227 = 83238
17 + 83221 = 83238
19 + 83219 = 83238
31 + 83207 = 83238
61 + 83177 = 83238
101 + 83137 = 83238

Showing the first eight; more decompositions exist.
