Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19426, here are decompositions:
- 3 + 19423 = 19426
- 5 + 19421 = 19426
- 23 + 19403 = 19426
- 47 + 19379 = 19426
- 53 + 19373 = 19426
- 107 + 19319 = 19426
- 137 + 19289 = 19426
- 167 + 19259 = 19426
Showing the first eight; more decompositions exist.
