Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526186, here are decompositions:
- 103 + 31526083 = 31526186
- 229 + 31525957 = 31526186
- 277 + 31525909 = 31526186
- 283 + 31525903 = 31526186
- 337 + 31525849 = 31526186
- 409 + 31525777 = 31526186
- 463 + 31525723 = 31526186
- 487 + 31525699 = 31526186
Showing the first eight; more decompositions exist.
