Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118720, here are decompositions:
- 3 + 118717 = 118720
- 11 + 118709 = 118720
- 29 + 118691 = 118720
- 47 + 118673 = 118720
- 59 + 118661 = 118720
- 101 + 118619 = 118720
- 131 + 118589 = 118720
- 137 + 118583 = 118720
Showing the first eight; more decompositions exist.
