Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2554, here are decompositions:

3 + 2551 = 2554
5 + 2549 = 2554
11 + 2543 = 2554
23 + 2531 = 2554
107 + 2447 = 2554
113 + 2441 = 2554
131 + 2423 = 2554
137 + 2417 = 2554

Showing the first eight; more decompositions exist.
