Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25542, here are decompositions:

5 + 25537 = 25542
19 + 25523 = 25542
71 + 25471 = 25542
73 + 25469 = 25542
79 + 25463 = 25542
89 + 25453 = 25542
103 + 25439 = 25542
131 + 25411 = 25542

Showing the first eight; more decompositions exist.
