Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143066, here are decompositions:
- 3 + 143063 = 143066
- 13 + 143053 = 143066
- 73 + 142993 = 143066
- 97 + 142969 = 143066
- 103 + 142963 = 143066
- 127 + 142939 = 143066
- 163 + 142903 = 143066
- 193 + 142873 = 143066
Showing the first eight; more decompositions exist.
