Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51286, here are decompositions:

3 + 51283 = 51286
23 + 51263 = 51286
29 + 51257 = 51286
47 + 51239 = 51286
83 + 51203 = 51286
89 + 51197 = 51286
149 + 51137 = 51286
227 + 51059 = 51286

Showing the first eight; more decompositions exist.
