Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4284, here are decompositions:

11 + 4273 = 4284
13 + 4271 = 4284
23 + 4261 = 4284
31 + 4253 = 4284
41 + 4243 = 4284
43 + 4241 = 4284
53 + 4231 = 4284
67 + 4217 = 4284

Showing the first eight; more decompositions exist.
