Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163684, here are decompositions:
- 5 + 163679 = 163684
- 11 + 163673 = 163684
- 23 + 163661 = 163684
- 41 + 163643 = 163684
- 47 + 163637 = 163684
- 71 + 163613 = 163684
- 83 + 163601 = 163684
- 167 + 163517 = 163684
Showing the first eight; more decompositions exist.
