Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2526, here are decompositions:

5 + 2521 = 2526
23 + 2503 = 2526
53 + 2473 = 2526
59 + 2467 = 2526
67 + 2459 = 2526
79 + 2447 = 2526
89 + 2437 = 2526
103 + 2423 = 2526

Showing the first eight; more decompositions exist.
