Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2118, here are decompositions:
- 5 + 2113 = 2118
- 7 + 2111 = 2118
- 19 + 2099 = 2118
- 29 + 2089 = 2118
- 31 + 2087 = 2118
- 37 + 2081 = 2118
- 79 + 2039 = 2118
- 89 + 2029 = 2118
Showing the first eight; more decompositions exist.
