Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547122, here are decompositions:
- 29 + 31547093 = 31547122
- 59 + 31547063 = 31547122
- 83 + 31547039 = 31547122
- 401 + 31546721 = 31547122
- 461 + 31546661 = 31547122
- 521 + 31546601 = 31547122
- 569 + 31546553 = 31547122
- 653 + 31546469 = 31547122
Showing the first eight; more decompositions exist.
