Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168756, here are decompositions:
- 13 + 168743 = 168756
- 19 + 168737 = 168756
- 37 + 168719 = 168756
- 43 + 168713 = 168756
- 59 + 168697 = 168756
- 79 + 168677 = 168756
- 83 + 168673 = 168756
- 113 + 168643 = 168756
Showing the first eight; more decompositions exist.
