Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87146, here are decompositions:
- 13 + 87133 = 87146
- 43 + 87103 = 87146
- 97 + 87049 = 87146
- 109 + 87037 = 87146
- 223 + 86923 = 87146
- 277 + 86869 = 87146
- 379 + 86767 = 87146
- 457 + 86689 = 87146
Showing the first eight; more decompositions exist.
