Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526866, here are decompositions:
- 3 + 31526863 = 31526866
- 47 + 31526819 = 31526866
- 89 + 31526777 = 31526866
- 113 + 31526753 = 31526866
- 197 + 31526669 = 31526866
- 233 + 31526633 = 31526866
- 263 + 31526603 = 31526866
- 389 + 31526477 = 31526866
Showing the first eight; more decompositions exist.
