Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477600, here are decompositions:
- 17 + 31477583 = 31477600
- 23 + 31477577 = 31477600
- 29 + 31477571 = 31477600
- 47 + 31477553 = 31477600
- 173 + 31477427 = 31477600
- 251 + 31477349 = 31477600
- 311 + 31477289 = 31477600
- 419 + 31477181 = 31477600
Showing the first eight; more decompositions exist.
