Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156790, here are decompositions:
- 41 + 156749 = 156790
- 71 + 156719 = 156790
- 83 + 156707 = 156790
- 107 + 156683 = 156790
- 113 + 156677 = 156790
- 131 + 156659 = 156790
- 149 + 156641 = 156790
- 167 + 156623 = 156790
Showing the first eight; more decompositions exist.
