Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25524, here are decompositions:

53 + 25471 = 25524
61 + 25463 = 25524
67 + 25457 = 25524
71 + 25453 = 25524
101 + 25423 = 25524
113 + 25411 = 25524
151 + 25373 = 25524
157 + 25367 = 25524

Showing the first eight; more decompositions exist.
