Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2454, here are decompositions:

7 + 2447 = 2454
13 + 2441 = 2454
17 + 2437 = 2454
31 + 2423 = 2454
37 + 2417 = 2454
43 + 2411 = 2454
61 + 2393 = 2454
71 + 2383 = 2454

Showing the first eight; more decompositions exist.
