Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11250, here are decompositions:

7 + 11243 = 11250
11 + 11239 = 11250
37 + 11213 = 11250
53 + 11197 = 11250
73 + 11177 = 11250
79 + 11171 = 11250
89 + 11161 = 11250
101 + 11149 = 11250

Showing the first eight; more decompositions exist.
