Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47018, here are decompositions:
- 61 + 46957 = 47018
- 151 + 46867 = 47018
- 157 + 46861 = 47018
- 199 + 46819 = 47018
- 211 + 46807 = 47018
- 271 + 46747 = 47018
- 331 + 46687 = 47018
- 337 + 46681 = 47018
Showing the first eight; more decompositions exist.
