Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25266, here are decompositions:

5 + 25261 = 25266
13 + 25253 = 25266
19 + 25247 = 25266
23 + 25243 = 25266
29 + 25237 = 25266
37 + 25229 = 25266
47 + 25219 = 25266
83 + 25183 = 25266

Showing the first eight; more decompositions exist.
