Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79986, here are decompositions:
- 7 + 79979 = 79986
- 13 + 79973 = 79986
- 19 + 79967 = 79986
- 43 + 79943 = 79986
- 47 + 79939 = 79986
- 79 + 79907 = 79986
- 83 + 79903 = 79986
- 97 + 79889 = 79986
Showing the first eight; more decompositions exist.
