Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12250, here are decompositions:

11 + 12239 = 12250
23 + 12227 = 12250
47 + 12203 = 12250
53 + 12197 = 12250
89 + 12161 = 12250
101 + 12149 = 12250
107 + 12143 = 12250
131 + 12119 = 12250

Showing the first eight; more decompositions exist.
