Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2286, here are decompositions:

5 + 2281 = 2286
13 + 2273 = 2286
17 + 2269 = 2286
19 + 2267 = 2286
43 + 2243 = 2286
47 + 2239 = 2286
73 + 2213 = 2286
79 + 2207 = 2286

Showing the first eight; more decompositions exist.
