Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159726, here are decompositions:
- 5 + 159721 = 159726
- 19 + 159707 = 159726
- 29 + 159697 = 159726
- 43 + 159683 = 159726
- 53 + 159673 = 159726
- 59 + 159667 = 159726
- 97 + 159629 = 159726
- 103 + 159623 = 159726
Showing the first eight; more decompositions exist.
