Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3480, here are decompositions:

11 + 3469 = 3480
13 + 3467 = 3480
17 + 3463 = 3480
19 + 3461 = 3480
23 + 3457 = 3480
31 + 3449 = 3480
47 + 3433 = 3480
67 + 3413 = 3480

Showing the first eight; more decompositions exist.
