Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25340, here are decompositions:

19 + 25321 = 25340
31 + 25309 = 25340
37 + 25303 = 25340
79 + 25261 = 25340
97 + 25243 = 25340
103 + 25237 = 25340
151 + 25189 = 25340
157 + 25183 = 25340

Showing the first eight; more decompositions exist.
