Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143106, here are decompositions:
- 13 + 143093 = 143106
- 43 + 143063 = 143106
- 53 + 143053 = 143106
- 113 + 142993 = 143106
- 127 + 142979 = 143106
- 137 + 142969 = 143106
- 157 + 142949 = 143106
- 167 + 142939 = 143106
Showing the first eight; more decompositions exist.
