Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25210, here are decompositions:

41 + 25169 = 25210
47 + 25163 = 25210
83 + 25127 = 25210
89 + 25121 = 25210
113 + 25097 = 25210
137 + 25073 = 25210
173 + 25037 = 25210
179 + 25031 = 25210

Showing the first eight; more decompositions exist.
