Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25310, here are decompositions:

3 + 25307 = 25310
7 + 25303 = 25310
67 + 25243 = 25310
73 + 25237 = 25310
127 + 25183 = 25310
139 + 25171 = 25310
157 + 25153 = 25310
163 + 25147 = 25310

Showing the first eight; more decompositions exist.
