Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22686, here are decompositions:
- 7 + 22679 = 22686
- 17 + 22669 = 22686
- 43 + 22643 = 22686
- 47 + 22639 = 22686
- 67 + 22619 = 22686
- 73 + 22613 = 22686
- 113 + 22573 = 22686
- 137 + 22549 = 22686
Showing the first eight; more decompositions exist.
