Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83428, here are decompositions:

5 + 83423 = 83428
11 + 83417 = 83428
29 + 83399 = 83428
71 + 83357 = 83428
89 + 83339 = 83428
197 + 83231 = 83428
251 + 83177 = 83428
311 + 83117 = 83428

Showing the first eight; more decompositions exist.
