Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83220, here are decompositions:

13 + 83207 = 83220
17 + 83203 = 83220
43 + 83177 = 83220
83 + 83137 = 83220
103 + 83117 = 83220
127 + 83093 = 83220
131 + 83089 = 83220
149 + 83071 = 83220

Showing the first eight; more decompositions exist.
