Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4266, here are decompositions:

5 + 4261 = 4266
7 + 4259 = 4266
13 + 4253 = 4266
23 + 4243 = 4266
37 + 4229 = 4266
47 + 4219 = 4266
89 + 4177 = 4266
107 + 4159 = 4266

Showing the first eight; more decompositions exist.
