Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20186, here are decompositions:
- 3 + 20183 = 20186
- 13 + 20173 = 20186
- 37 + 20149 = 20186
- 43 + 20143 = 20186
- 73 + 20113 = 20186
- 79 + 20107 = 20186
- 97 + 20089 = 20186
- 139 + 20047 = 20186
Showing the first eight; more decompositions exist.
