Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25450, here are decompositions:

3 + 25447 = 25450
11 + 25439 = 25450
41 + 25409 = 25450
59 + 25391 = 25450
83 + 25367 = 25450
101 + 25349 = 25450
107 + 25343 = 25450
149 + 25301 = 25450

Showing the first eight; more decompositions exist.
