Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123426, here are decompositions:
- 7 + 123419 = 123426
- 19 + 123407 = 123426
- 29 + 123397 = 123426
- 47 + 123379 = 123426
- 53 + 123373 = 123426
- 103 + 123323 = 123426
- 137 + 123289 = 123426
- 157 + 123269 = 123426
Showing the first eight; more decompositions exist.
