Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18126, here are decompositions:
- 5 + 18121 = 18126
- 7 + 18119 = 18126
- 29 + 18097 = 18126
- 37 + 18089 = 18126
- 67 + 18059 = 18126
- 79 + 18047 = 18126
- 83 + 18043 = 18126
- 113 + 18013 = 18126
Showing the first eight; more decompositions exist.
