Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118728, here are decompositions:
- 11 + 118717 = 118728
- 19 + 118709 = 118728
- 37 + 118691 = 118728
- 41 + 118687 = 118728
- 47 + 118681 = 118728
- 59 + 118669 = 118728
- 67 + 118661 = 118728
- 107 + 118621 = 118728
Showing the first eight; more decompositions exist.
