Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2382, here are decompositions:

5 + 2377 = 2382
11 + 2371 = 2382
31 + 2351 = 2382
41 + 2341 = 2382
43 + 2339 = 2382
71 + 2311 = 2382
73 + 2309 = 2382
89 + 2293 = 2382

Showing the first eight; more decompositions exist.
