Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2380, here are decompositions:

3 + 2377 = 2380
23 + 2357 = 2380
29 + 2351 = 2380
41 + 2339 = 2380
47 + 2333 = 2380
71 + 2309 = 2380
83 + 2297 = 2380
107 + 2273 = 2380

Showing the first eight; more decompositions exist.
