Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99872, here are decompositions:
- 13 + 99859 = 99872
- 43 + 99829 = 99872
- 79 + 99793 = 99872
- 139 + 99733 = 99872
- 151 + 99721 = 99872
- 163 + 99709 = 99872
- 193 + 99679 = 99872
- 211 + 99661 = 99872
Showing the first eight; more decompositions exist.
