Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83380, here are decompositions:

23 + 83357 = 83380
41 + 83339 = 83380
107 + 83273 = 83380
113 + 83267 = 83380
137 + 83243 = 83380
149 + 83231 = 83380
173 + 83207 = 83380
263 + 83117 = 83380

Showing the first eight; more decompositions exist.
