Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2418, here are decompositions:

7 + 2411 = 2418
19 + 2399 = 2418
29 + 2389 = 2418
37 + 2381 = 2418
41 + 2377 = 2418
47 + 2371 = 2418
61 + 2357 = 2418
67 + 2351 = 2418

Showing the first eight; more decompositions exist.
