Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25230, here are decompositions:

11 + 25219 = 25230
41 + 25189 = 25230
47 + 25183 = 25230
59 + 25171 = 25230
61 + 25169 = 25230
67 + 25163 = 25230
83 + 25147 = 25230
103 + 25127 = 25230

Showing the first eight; more decompositions exist.
