Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25002, here are decompositions:

13 + 24989 = 25002
23 + 24979 = 25002
31 + 24971 = 25002
59 + 24943 = 25002
79 + 24923 = 25002
83 + 24919 = 25002
113 + 24889 = 25002
151 + 24851 = 25002

Showing the first eight; more decompositions exist.
