Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25020, here are decompositions:

7 + 25013 = 25020
31 + 24989 = 25020
41 + 24979 = 25020
43 + 24977 = 25020
53 + 24967 = 25020
67 + 24953 = 25020
97 + 24923 = 25020
101 + 24919 = 25020

Showing the first eight; more decompositions exist.
