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.
