Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91020, here are decompositions:
- 11 + 91009 = 91020
- 23 + 90997 = 91020
- 31 + 90989 = 91020
- 43 + 90977 = 91020
- 73 + 90947 = 91020
- 89 + 90931 = 91020
- 103 + 90917 = 91020
- 109 + 90911 = 91020
Showing the first eight; more decompositions exist.
