Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79800, here are decompositions:
- 23 + 79777 = 79800
- 31 + 79769 = 79800
- 43 + 79757 = 79800
- 101 + 79699 = 79800
- 103 + 79697 = 79800
- 107 + 79693 = 79800
- 109 + 79691 = 79800
- 113 + 79687 = 79800
Showing the first eight; more decompositions exist.
