Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79868, here are decompositions:
- 7 + 79861 = 79868
- 67 + 79801 = 79868
- 181 + 79687 = 79868
- 199 + 79669 = 79868
- 211 + 79657 = 79868
- 241 + 79627 = 79868
- 307 + 79561 = 79868
- 331 + 79537 = 79868
Showing the first eight; more decompositions exist.
