Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19464, here are decompositions:
- 7 + 19457 = 19464
- 17 + 19447 = 19464
- 23 + 19441 = 19464
- 31 + 19433 = 19464
- 37 + 19427 = 19464
- 41 + 19423 = 19464
- 43 + 19421 = 19464
- 47 + 19417 = 19464
Showing the first eight; more decompositions exist.
