Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99818, here are decompositions:
- 31 + 99787 = 99818
- 97 + 99721 = 99818
- 109 + 99709 = 99818
- 139 + 99679 = 99818
- 151 + 99667 = 99818
- 157 + 99661 = 99818
- 211 + 99607 = 99818
- 241 + 99577 = 99818
Showing the first eight; more decompositions exist.
