Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2398, here are decompositions:

5 + 2393 = 2398
17 + 2381 = 2398
41 + 2357 = 2398
47 + 2351 = 2398
59 + 2339 = 2398
89 + 2309 = 2398
101 + 2297 = 2398
131 + 2267 = 2398

Showing the first eight; more decompositions exist.
