Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18274, here are decompositions:
- 5 + 18269 = 18274
- 17 + 18257 = 18274
- 23 + 18251 = 18274
- 41 + 18233 = 18274
- 83 + 18191 = 18274
- 131 + 18143 = 18274
- 197 + 18077 = 18274
- 227 + 18047 = 18274
Showing the first eight; more decompositions exist.
