Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80458, here are decompositions:
- 11 + 80447 = 80458
- 29 + 80429 = 80458
- 71 + 80387 = 80458
- 89 + 80369 = 80458
- 149 + 80309 = 80458
- 179 + 80279 = 80458
- 227 + 80231 = 80458
- 251 + 80207 = 80458
Showing the first eight; more decompositions exist.
