Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3280, here are decompositions:

23 + 3257 = 3280
29 + 3251 = 3280
59 + 3221 = 3280
71 + 3209 = 3280
89 + 3191 = 3280
113 + 3167 = 3280
191 + 3089 = 3280
197 + 3083 = 3280

Showing the first eight; more decompositions exist.
