Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008686, here are decompositions:
- 73 + 1008613 = 1008686
- 79 + 1008607 = 1008686
- 97 + 1008589 = 1008686
- 139 + 1008547 = 1008686
- 193 + 1008493 = 1008686
- 277 + 1008409 = 1008686
- 307 + 1008379 = 1008686
- 313 + 1008373 = 1008686
Showing the first eight; more decompositions exist.
