Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4288, here are decompositions:
- 5 + 4283 = 4288
- 17 + 4271 = 4288
- 29 + 4259 = 4288
- 47 + 4241 = 4288
- 59 + 4229 = 4288
- 71 + 4217 = 4288
- 131 + 4157 = 4288
- 149 + 4139 = 4288
Showing the first eight; more decompositions exist.
