Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2548, here are decompositions:

5 + 2543 = 2548
17 + 2531 = 2548
71 + 2477 = 2548
89 + 2459 = 2548
101 + 2447 = 2548
107 + 2441 = 2548
131 + 2417 = 2548
137 + 2411 = 2548

Showing the first eight; more decompositions exist.
