Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2506, here are decompositions:

3 + 2503 = 2506
29 + 2477 = 2506
47 + 2459 = 2506
59 + 2447 = 2506
83 + 2423 = 2506
89 + 2417 = 2506
107 + 2399 = 2506
113 + 2393 = 2506

Showing the first eight; more decompositions exist.
