Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536726, here are decompositions:
- 7 + 31536719 = 31536726
- 19 + 31536707 = 31536726
- 29 + 31536697 = 31536726
- 97 + 31536629 = 31536726
- 113 + 31536613 = 31536726
- 197 + 31536529 = 31536726
- 227 + 31536499 = 31536726
- 367 + 31536359 = 31536726
Showing the first eight; more decompositions exist.
