Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163744, here are decompositions:
- 3 + 163741 = 163744
- 11 + 163733 = 163744
- 47 + 163697 = 163744
- 71 + 163673 = 163744
- 83 + 163661 = 163744
- 101 + 163643 = 163744
- 107 + 163637 = 163744
- 131 + 163613 = 163744
Showing the first eight; more decompositions exist.
