Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77168, here are decompositions:
- 31 + 77137 = 77168
- 67 + 77101 = 77168
- 127 + 77041 = 77168
- 139 + 77029 = 77168
- 151 + 77017 = 77168
- 331 + 76837 = 77168
- 337 + 76831 = 77168
- 349 + 76819 = 77168
Showing the first eight; more decompositions exist.
