Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2428, here are decompositions:

5 + 2423 = 2428
11 + 2417 = 2428
17 + 2411 = 2428
29 + 2399 = 2428
47 + 2381 = 2428
71 + 2357 = 2428
89 + 2339 = 2428
131 + 2297 = 2428

Showing the first eight; more decompositions exist.
