Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18246, here are decompositions:
- 13 + 18233 = 18246
- 17 + 18229 = 18246
- 23 + 18223 = 18246
- 29 + 18217 = 18246
- 47 + 18199 = 18246
- 97 + 18149 = 18246
- 103 + 18143 = 18246
- 113 + 18133 = 18246
Showing the first eight; more decompositions exist.
