Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4206, here are decompositions:
- 5 + 4201 = 4206
- 29 + 4177 = 4206
- 47 + 4159 = 4206
- 53 + 4153 = 4206
- 67 + 4139 = 4206
- 73 + 4133 = 4206
- 79 + 4127 = 4206
- 107 + 4099 = 4206
Showing the first eight; more decompositions exist.
