Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526830, here are decompositions:
- 11 + 31526819 = 31526830
- 53 + 31526777 = 31526830
- 59 + 31526771 = 31526830
- 107 + 31526723 = 31526830
- 197 + 31526633 = 31526830
- 227 + 31526603 = 31526830
- 353 + 31526477 = 31526830
- 443 + 31526387 = 31526830
Showing the first eight; more decompositions exist.
