Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527894, here are decompositions:
- 7 + 31527887 = 31527894
- 67 + 31527827 = 31527894
- 107 + 31527787 = 31527894
- 113 + 31527781 = 31527894
- 191 + 31527703 = 31527894
- 193 + 31527701 = 31527894
- 197 + 31527697 = 31527894
- 311 + 31527583 = 31527894
Showing the first eight; more decompositions exist.
