Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2328, here are decompositions:

17 + 2311 = 2328
19 + 2309 = 2328
31 + 2297 = 2328
41 + 2287 = 2328
47 + 2281 = 2328
59 + 2269 = 2328
61 + 2267 = 2328
89 + 2239 = 2328

Showing the first eight; more decompositions exist.
