Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18324, here are decompositions:
- 11 + 18313 = 18324
- 13 + 18311 = 18324
- 17 + 18307 = 18324
- 23 + 18301 = 18324
- 37 + 18287 = 18324
- 67 + 18257 = 18324
- 71 + 18253 = 18324
- 73 + 18251 = 18324
Showing the first eight; more decompositions exist.
