Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163318, here are decompositions:
- 11 + 163307 = 163318
- 59 + 163259 = 163318
- 107 + 163211 = 163318
- 137 + 163181 = 163318
- 149 + 163169 = 163318
- 167 + 163151 = 163318
- 191 + 163127 = 163318
- 257 + 163061 = 163318
Showing the first eight; more decompositions exist.
