Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25240, here are decompositions:

3 + 25237 = 25240
11 + 25229 = 25240
71 + 25169 = 25240
113 + 25127 = 25240
167 + 25073 = 25240
227 + 25013 = 25240
251 + 24989 = 25240
263 + 24977 = 25240

Showing the first eight; more decompositions exist.
