Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2574, here are decompositions:

17 + 2557 = 2574
23 + 2551 = 2574
31 + 2543 = 2574
43 + 2531 = 2574
53 + 2521 = 2574
71 + 2503 = 2574
97 + 2477 = 2574
101 + 2473 = 2574

Showing the first eight; more decompositions exist.
