Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25590, here are decompositions:

7 + 25583 = 25590
11 + 25579 = 25590
13 + 25577 = 25590
29 + 25561 = 25590
53 + 25537 = 25590
67 + 25523 = 25590
127 + 25463 = 25590
137 + 25453 = 25590

Showing the first eight; more decompositions exist.
