Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526986, here are decompositions:
- 47 + 31526939 = 31526986
- 59 + 31526927 = 31526986
- 83 + 31526903 = 31526986
- 107 + 31526879 = 31526986
- 167 + 31526819 = 31526986
- 233 + 31526753 = 31526986
- 263 + 31526723 = 31526986
- 317 + 31526669 = 31526986
Showing the first eight; more decompositions exist.
