Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477690, here are decompositions:
- 107 + 31477583 = 31477690
- 113 + 31477577 = 31477690
- 137 + 31477553 = 31477690
- 263 + 31477427 = 31477690
- 311 + 31477379 = 31477690
- 389 + 31477301 = 31477690
- 401 + 31477289 = 31477690
- 509 + 31477181 = 31477690
Showing the first eight; more decompositions exist.
