Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163768, here are decompositions:
- 71 + 163697 = 163768
- 89 + 163679 = 163768
- 107 + 163661 = 163768
- 131 + 163637 = 163768
- 167 + 163601 = 163768
- 251 + 163517 = 163768
- 281 + 163487 = 163768
- 359 + 163409 = 163768
Showing the first eight; more decompositions exist.
