Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4188, here are decompositions:
- 11 + 4177 = 4188
- 29 + 4159 = 4188
- 31 + 4157 = 4188
- 59 + 4129 = 4188
- 61 + 4127 = 4188
- 89 + 4099 = 4188
- 97 + 4091 = 4188
- 109 + 4079 = 4188
Showing the first eight; more decompositions exist.
