Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91026, here are decompositions:
- 7 + 91019 = 91026
- 17 + 91009 = 91026
- 29 + 90997 = 91026
- 37 + 90989 = 91026
- 79 + 90947 = 91026
- 109 + 90917 = 91026
- 139 + 90887 = 91026
- 163 + 90863 = 91026
Showing the first eight; more decompositions exist.
