Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25280, here are decompositions:

19 + 25261 = 25280
37 + 25243 = 25280
43 + 25237 = 25280
61 + 25219 = 25280
97 + 25183 = 25280
109 + 25171 = 25280
127 + 25153 = 25280
163 + 25117 = 25280

Showing the first eight; more decompositions exist.
