Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2550, here are decompositions:

7 + 2543 = 2550
11 + 2539 = 2550
19 + 2531 = 2550
29 + 2521 = 2550
47 + 2503 = 2550
73 + 2477 = 2550
83 + 2467 = 2550
103 + 2447 = 2550

Showing the first eight; more decompositions exist.
