Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2358, here are decompositions:

7 + 2351 = 2358
11 + 2347 = 2358
17 + 2341 = 2358
19 + 2339 = 2358
47 + 2311 = 2358
61 + 2297 = 2358
71 + 2287 = 2358
89 + 2269 = 2358

Showing the first eight; more decompositions exist.
