Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17578, here are decompositions:
- 5 + 17573 = 17578
- 59 + 17519 = 17578
- 89 + 17489 = 17578
- 101 + 17477 = 17578
- 107 + 17471 = 17578
- 191 + 17387 = 17578
- 227 + 17351 = 17578
- 251 + 17327 = 17578
Showing the first eight; more decompositions exist.
