Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99920, here are decompositions:
- 13 + 99907 = 99920
- 19 + 99901 = 99920
- 43 + 99877 = 99920
- 61 + 99859 = 99920
- 97 + 99823 = 99920
- 103 + 99817 = 99920
- 127 + 99793 = 99920
- 199 + 99721 = 99920
Showing the first eight; more decompositions exist.
