Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2478, here are decompositions:

5 + 2473 = 2478
11 + 2467 = 2478
19 + 2459 = 2478
31 + 2447 = 2478
37 + 2441 = 2478
41 + 2437 = 2478
61 + 2417 = 2478
67 + 2411 = 2478

Showing the first eight; more decompositions exist.
