Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89930, here are decompositions:
- 7 + 89923 = 89930
- 13 + 89917 = 89930
- 31 + 89899 = 89930
- 97 + 89833 = 89930
- 109 + 89821 = 89930
- 151 + 89779 = 89930
- 163 + 89767 = 89930
- 241 + 89689 = 89930
Showing the first eight; more decompositions exist.
