Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25506, here are decompositions:

37 + 25469 = 25506
43 + 25463 = 25506
53 + 25453 = 25506
59 + 25447 = 25506
67 + 25439 = 25506
83 + 25423 = 25506
97 + 25409 = 25506
139 + 25367 = 25506

Showing the first eight; more decompositions exist.
