Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536936, here are decompositions:
- 19 + 31536917 = 31536936
- 73 + 31536863 = 31536936
- 89 + 31536847 = 31536936
- 107 + 31536829 = 31536936
- 113 + 31536823 = 31536936
- 163 + 31536773 = 31536936
- 229 + 31536707 = 31536936
- 239 + 31536697 = 31536936
Showing the first eight; more decompositions exist.
