Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477710, here are decompositions:
- 13 + 31477697 = 31477710
- 41 + 31477669 = 31477710
- 53 + 31477657 = 31477710
- 107 + 31477603 = 31477710
- 127 + 31477583 = 31477710
- 139 + 31477571 = 31477710
- 149 + 31477561 = 31477710
- 157 + 31477553 = 31477710
Showing the first eight; more decompositions exist.
