Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83278, here are decompositions:

5 + 83273 = 83278
11 + 83267 = 83278
47 + 83231 = 83278
59 + 83219 = 83278
71 + 83207 = 83278
101 + 83177 = 83278
269 + 83009 = 83278
281 + 82997 = 83278

Showing the first eight; more decompositions exist.
