Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168744, here are decompositions:
- 7 + 168737 = 168744
- 13 + 168731 = 168744
- 31 + 168713 = 168744
- 47 + 168697 = 168744
- 67 + 168677 = 168744
- 71 + 168673 = 168744
- 101 + 168643 = 168744
- 113 + 168631 = 168744
Showing the first eight; more decompositions exist.
