Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99918, here are decompositions:
- 11 + 99907 = 99918
- 17 + 99901 = 99918
- 37 + 99881 = 99918
- 41 + 99877 = 99918
- 47 + 99871 = 99918
- 59 + 99859 = 99918
- 79 + 99839 = 99918
- 89 + 99829 = 99918
Showing the first eight; more decompositions exist.
