Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2388, here are decompositions:

5 + 2383 = 2388
7 + 2381 = 2388
11 + 2377 = 2388
17 + 2371 = 2388
31 + 2357 = 2388
37 + 2351 = 2388
41 + 2347 = 2388
47 + 2341 = 2388

Showing the first eight; more decompositions exist.
