Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101728, here are decompositions:
- 5 + 101723 = 101728
- 47 + 101681 = 101728
- 101 + 101627 = 101728
- 167 + 101561 = 101728
- 191 + 101537 = 101728
- 197 + 101531 = 101728
- 227 + 101501 = 101728
- 239 + 101489 = 101728
Showing the first eight; more decompositions exist.
