Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25158, here are decompositions:

5 + 25153 = 25158
11 + 25147 = 25158
31 + 25127 = 25158
37 + 25121 = 25158
41 + 25117 = 25158
47 + 25111 = 25158
61 + 25097 = 25158
71 + 25087 = 25158

Showing the first eight; more decompositions exist.
