Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99900, here are decompositions:
- 19 + 99881 = 99900
- 23 + 99877 = 99900
- 29 + 99871 = 99900
- 41 + 99859 = 99900
- 61 + 99839 = 99900
- 67 + 99833 = 99900
- 71 + 99829 = 99900
- 83 + 99817 = 99900
Showing the first eight; more decompositions exist.
