Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10250, here are decompositions:

3 + 10247 = 10250
7 + 10243 = 10250
73 + 10177 = 10250
109 + 10141 = 10250
139 + 10111 = 10250
151 + 10099 = 10250
157 + 10093 = 10250
181 + 10069 = 10250

Showing the first eight; more decompositions exist.
