Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67280, here are decompositions:

7 + 67273 = 67280
19 + 67261 = 67280
61 + 67219 = 67280
67 + 67213 = 67280
127 + 67153 = 67280
139 + 67141 = 67280
151 + 67129 = 67280
223 + 67057 = 67280

Showing the first eight; more decompositions exist.
