Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2406, here are decompositions:

7 + 2399 = 2406
13 + 2393 = 2406
17 + 2389 = 2406
23 + 2383 = 2406
29 + 2377 = 2406
59 + 2347 = 2406
67 + 2339 = 2406
73 + 2333 = 2406

Showing the first eight; more decompositions exist.
