Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2370, here are decompositions:

13 + 2357 = 2370
19 + 2351 = 2370
23 + 2347 = 2370
29 + 2341 = 2370
31 + 2339 = 2370
37 + 2333 = 2370
59 + 2311 = 2370
61 + 2309 = 2370

Showing the first eight; more decompositions exist.
