Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4158, here are decompositions:
- 5 + 4153 = 4158
- 19 + 4139 = 4158
- 29 + 4129 = 4158
- 31 + 4127 = 4158
- 47 + 4111 = 4158
- 59 + 4099 = 4158
- 67 + 4091 = 4158
- 79 + 4079 = 4158
Showing the first eight; more decompositions exist.
