Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42406, here are decompositions:
- 3 + 42403 = 42406
- 47 + 42359 = 42406
- 83 + 42323 = 42406
- 107 + 42299 = 42406
- 113 + 42293 = 42406
- 149 + 42257 = 42406
- 167 + 42239 = 42406
- 179 + 42227 = 42406
Showing the first eight; more decompositions exist.
