Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497926, here are decompositions:
- 43 + 31497883 = 31497926
- 67 + 31497859 = 31497926
- 199 + 31497727 = 31497926
- 349 + 31497577 = 31497926
- 367 + 31497559 = 31497926
- 379 + 31497547 = 31497926
- 457 + 31497469 = 31497926
- 463 + 31497463 = 31497926
Showing the first eight; more decompositions exist.
