Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40166, here are decompositions:
- 3 + 40163 = 40166
- 13 + 40153 = 40166
- 37 + 40129 = 40166
- 43 + 40123 = 40166
- 67 + 40099 = 40166
- 73 + 40093 = 40166
- 79 + 40087 = 40166
- 103 + 40063 = 40166
Showing the first eight; more decompositions exist.
