Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19366, here are decompositions:
- 47 + 19319 = 19366
- 107 + 19259 = 19366
- 227 + 19139 = 19366
- 293 + 19073 = 19366
- 353 + 19013 = 19366
- 419 + 18947 = 19366
- 449 + 18917 = 19366
- 467 + 18899 = 19366
Showing the first eight; more decompositions exist.
