Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163146, here are decompositions:
- 17 + 163129 = 163146
- 19 + 163127 = 163146
- 29 + 163117 = 163146
- 37 + 163109 = 163146
- 83 + 163063 = 163146
- 127 + 163019 = 163146
- 149 + 162997 = 163146
- 157 + 162989 = 163146
Showing the first eight; more decompositions exist.
