Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78166, here are decompositions:
- 3 + 78163 = 78166
- 29 + 78137 = 78166
- 107 + 78059 = 78166
- 149 + 78017 = 78166
- 167 + 77999 = 78166
- 197 + 77969 = 78166
- 233 + 77933 = 78166
- 317 + 77849 = 78166
Showing the first eight; more decompositions exist.
