Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163306, here are decompositions:
- 47 + 163259 = 163306
- 83 + 163223 = 163306
- 107 + 163199 = 163306
- 113 + 163193 = 163306
- 137 + 163169 = 163306
- 179 + 163127 = 163306
- 197 + 163109 = 163306
- 317 + 162989 = 163306
Showing the first eight; more decompositions exist.
