Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2356, here are decompositions:

5 + 2351 = 2356
17 + 2339 = 2356
23 + 2333 = 2356
47 + 2309 = 2356
59 + 2297 = 2356
83 + 2273 = 2356
89 + 2267 = 2356
113 + 2243 = 2356

Showing the first eight; more decompositions exist.
