Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25018, here are decompositions:

5 + 25013 = 25018
29 + 24989 = 25018
41 + 24977 = 25018
47 + 24971 = 25018
101 + 24917 = 25018
167 + 24851 = 25018
197 + 24821 = 25018
251 + 24767 = 25018

Showing the first eight; more decompositions exist.
