Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79806, here are decompositions:
- 5 + 79801 = 79806
- 29 + 79777 = 79806
- 37 + 79769 = 79806
- 107 + 79699 = 79806
- 109 + 79697 = 79806
- 113 + 79693 = 79806
- 137 + 79669 = 79806
- 149 + 79657 = 79806
Showing the first eight; more decompositions exist.
