Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477750, here are decompositions:
- 53 + 31477697 = 31477750
- 167 + 31477583 = 31477750
- 173 + 31477577 = 31477750
- 179 + 31477571 = 31477750
- 197 + 31477553 = 31477750
- 401 + 31477349 = 31477750
- 449 + 31477301 = 31477750
- 461 + 31477289 = 31477750
Showing the first eight; more decompositions exist.
