Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4178, here are decompositions:
- 19 + 4159 = 4178
- 67 + 4111 = 4178
- 79 + 4099 = 4178
- 127 + 4051 = 4178
- 151 + 4027 = 4178
- 157 + 4021 = 4178
- 211 + 3967 = 4178
- 271 + 3907 = 4178
Showing the first eight; more decompositions exist.
