Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167178, here are decompositions:
- 5 + 167173 = 167178
- 19 + 167159 = 167178
- 29 + 167149 = 167178
- 59 + 167119 = 167178
- 61 + 167117 = 167178
- 71 + 167107 = 167178
- 79 + 167099 = 167178
- 97 + 167081 = 167178
Showing the first eight; more decompositions exist.
