Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142168, here are decompositions:
- 11 + 142157 = 142168
- 17 + 142151 = 142168
- 71 + 142097 = 142168
- 101 + 142067 = 142168
- 107 + 142061 = 142168
- 137 + 142031 = 142168
- 149 + 142019 = 142168
- 197 + 141971 = 142168
Showing the first eight; more decompositions exist.
