Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4286, here are decompositions:

3 + 4283 = 4286
13 + 4273 = 4286
43 + 4243 = 4286
67 + 4219 = 4286
109 + 4177 = 4286
127 + 4159 = 4286
157 + 4129 = 4286
193 + 4093 = 4286

Showing the first eight; more decompositions exist.
