Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105686, here are decompositions:
- 3 + 105683 = 105686
- 13 + 105673 = 105686
- 19 + 105667 = 105686
- 37 + 105649 = 105686
- 67 + 105619 = 105686
- 73 + 105613 = 105686
- 79 + 105607 = 105686
- 157 + 105529 = 105686
Showing the first eight; more decompositions exist.
