Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19446, here are decompositions:
- 5 + 19441 = 19446
- 13 + 19433 = 19446
- 17 + 19429 = 19446
- 19 + 19427 = 19446
- 23 + 19423 = 19446
- 29 + 19417 = 19446
- 43 + 19403 = 19446
- 59 + 19387 = 19446
Showing the first eight; more decompositions exist.
