Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118986, here are decompositions:
- 13 + 118973 = 118986
- 19 + 118967 = 118986
- 59 + 118927 = 118986
- 73 + 118913 = 118986
- 79 + 118907 = 118986
- 83 + 118903 = 118986
- 89 + 118897 = 118986
- 113 + 118873 = 118986
Showing the first eight; more decompositions exist.
