Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91788, here are decompositions:
- 7 + 91781 = 91788
- 17 + 91771 = 91788
- 31 + 91757 = 91788
- 97 + 91691 = 91788
- 149 + 91639 = 91788
- 157 + 91631 = 91788
- 167 + 91621 = 91788
- 197 + 91591 = 91788
Showing the first eight; more decompositions exist.
