Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17828, here are decompositions:
- 37 + 17791 = 17828
- 67 + 17761 = 17828
- 79 + 17749 = 17828
- 229 + 17599 = 17828
- 277 + 17551 = 17828
- 331 + 17497 = 17828
- 337 + 17491 = 17828
- 379 + 17449 = 17828
Showing the first eight; more decompositions exist.
