Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105728, here are decompositions:
- 37 + 105691 = 105728
- 61 + 105667 = 105728
- 79 + 105649 = 105728
- 109 + 105619 = 105728
- 127 + 105601 = 105728
- 199 + 105529 = 105728
- 211 + 105517 = 105728
- 229 + 105499 = 105728
Showing the first eight; more decompositions exist.
