Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77166, here are decompositions:
- 13 + 77153 = 77166
- 29 + 77137 = 77166
- 73 + 77093 = 77166
- 97 + 77069 = 77166
- 137 + 77029 = 77166
- 149 + 77017 = 77166
- 163 + 77003 = 77166
- 223 + 76943 = 77166
Showing the first eight; more decompositions exist.
