Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99730, here are decompositions:
- 11 + 99719 = 99730
- 17 + 99713 = 99730
- 23 + 99707 = 99730
- 41 + 99689 = 99730
- 107 + 99623 = 99730
- 149 + 99581 = 99730
- 167 + 99563 = 99730
- 179 + 99551 = 99730
Showing the first eight; more decompositions exist.
