Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25110, here are decompositions:

13 + 25097 = 25110
23 + 25087 = 25110
37 + 25073 = 25110
53 + 25057 = 25110
73 + 25037 = 25110
79 + 25031 = 25110
97 + 25013 = 25110
131 + 24979 = 25110

Showing the first eight; more decompositions exist.
