Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118828, here are decompositions:
- 29 + 118799 = 118828
- 41 + 118787 = 118828
- 71 + 118757 = 118828
- 89 + 118739 = 118828
- 137 + 118691 = 118828
- 167 + 118661 = 118828
- 239 + 118589 = 118828
- 257 + 118571 = 118828
Showing the first eight; more decompositions exist.
