Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57280, here are decompositions:
- 11 + 57269 = 57280
- 29 + 57251 = 57280
- 59 + 57221 = 57280
- 89 + 57191 = 57280
- 101 + 57179 = 57280
- 107 + 57173 = 57280
- 131 + 57149 = 57280
- 137 + 57143 = 57280
Showing the first eight; more decompositions exist.
