Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99942, here are decompositions:
- 13 + 99929 = 99942
- 19 + 99923 = 99942
- 41 + 99901 = 99942
- 61 + 99881 = 99942
- 71 + 99871 = 99942
- 83 + 99859 = 99942
- 103 + 99839 = 99942
- 109 + 99833 = 99942
Showing the first eight; more decompositions exist.
