Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91006, here are decompositions:
- 17 + 90989 = 91006
- 29 + 90977 = 91006
- 59 + 90947 = 91006
- 89 + 90917 = 91006
- 173 + 90833 = 91006
- 257 + 90749 = 91006
- 347 + 90659 = 91006
- 359 + 90647 = 91006
Showing the first eight; more decompositions exist.
