Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99840, here are decompositions:
- 7 + 99833 = 99840
- 11 + 99829 = 99840
- 17 + 99823 = 99840
- 23 + 99817 = 99840
- 31 + 99809 = 99840
- 47 + 99793 = 99840
- 53 + 99787 = 99840
- 73 + 99767 = 99840
Showing the first eight; more decompositions exist.
