Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2600, here are decompositions:

7 + 2593 = 2600
43 + 2557 = 2600
61 + 2539 = 2600
79 + 2521 = 2600
97 + 2503 = 2600
127 + 2473 = 2600
163 + 2437 = 2600
211 + 2389 = 2600

Showing the first eight; more decompositions exist.
