Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 119728, here are decompositions:
- 5 + 119723 = 119728
- 29 + 119699 = 119728
- 41 + 119687 = 119728
- 71 + 119657 = 119728
- 101 + 119627 = 119728
- 137 + 119591 = 119728
- 179 + 119549 = 119728
- 239 + 119489 = 119728
Showing the first eight; more decompositions exist.
