Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156724, here are decompositions:
- 5 + 156719 = 156724
- 17 + 156707 = 156724
- 41 + 156683 = 156724
- 47 + 156677 = 156724
- 53 + 156671 = 156724
- 83 + 156641 = 156724
- 101 + 156623 = 156724
- 131 + 156593 = 156724
Showing the first eight; more decompositions exist.
