Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449926, here are decompositions:
- 3 + 31449923 = 31449926
- 73 + 31449853 = 31449926
- 103 + 31449823 = 31449926
- 229 + 31449697 = 31449926
- 307 + 31449619 = 31449926
- 337 + 31449589 = 31449926
- 349 + 31449577 = 31449926
- 373 + 31449553 = 31449926
Showing the first eight; more decompositions exist.
