Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25104, here are decompositions:

7 + 25097 = 25104
17 + 25087 = 25104
31 + 25073 = 25104
47 + 25057 = 25104
67 + 25037 = 25104
71 + 25033 = 25104
73 + 25031 = 25104
127 + 24977 = 25104

Showing the first eight; more decompositions exist.
