Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25510, here are decompositions:

41 + 25469 = 25510
47 + 25463 = 25510
53 + 25457 = 25510
71 + 25439 = 25510
101 + 25409 = 25510
137 + 25373 = 25510
167 + 25343 = 25510
257 + 25253 = 25510

Showing the first eight; more decompositions exist.
