Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99684, here are decompositions:
- 5 + 99679 = 99684
- 17 + 99667 = 99684
- 23 + 99661 = 99684
- 41 + 99643 = 99684
- 61 + 99623 = 99684
- 73 + 99611 = 99684
- 103 + 99581 = 99684
- 107 + 99577 = 99684
Showing the first eight; more decompositions exist.
