Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526782, here are decompositions:
- 5 + 31526777 = 31526782
- 11 + 31526771 = 31526782
- 29 + 31526753 = 31526782
- 59 + 31526723 = 31526782
- 113 + 31526669 = 31526782
- 149 + 31526633 = 31526782
- 179 + 31526603 = 31526782
- 293 + 31526489 = 31526782
Showing the first eight; more decompositions exist.
