Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008688, here are decompositions:
- 29 + 1008659 = 1008688
- 71 + 1008617 = 1008688
- 101 + 1008587 = 1008688
- 251 + 1008437 = 1008688
- 269 + 1008419 = 1008688
- 281 + 1008407 = 1008688
- 431 + 1008257 = 1008688
- 449 + 1008239 = 1008688
Showing the first eight; more decompositions exist.
