Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2280, here are decompositions:

7 + 2273 = 2280
11 + 2269 = 2280
13 + 2267 = 2280
29 + 2251 = 2280
37 + 2243 = 2280
41 + 2239 = 2280
43 + 2237 = 2280
59 + 2221 = 2280

Showing the first eight; more decompositions exist.
