Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527040, here are decompositions:
- 23 + 31527017 = 31527040
- 29 + 31527011 = 31527040
- 101 + 31526939 = 31527040
- 113 + 31526927 = 31527040
- 137 + 31526903 = 31527040
- 263 + 31526777 = 31527040
- 269 + 31526771 = 31527040
- 317 + 31526723 = 31527040
Showing the first eight; more decompositions exist.
