Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118666, here are decompositions:
- 5 + 118661 = 118666
- 47 + 118619 = 118666
- 83 + 118583 = 118666
- 137 + 118529 = 118666
- 173 + 118493 = 118666
- 257 + 118409 = 118666
- 293 + 118373 = 118666
- 389 + 118277 = 118666
Showing the first eight; more decompositions exist.
