Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023686, here are decompositions:
- 43 + 1023643 = 1023686
- 109 + 1023577 = 1023686
- 199 + 1023487 = 1023686
- 277 + 1023409 = 1023686
- 373 + 1023313 = 1023686
- 397 + 1023289 = 1023686
- 409 + 1023277 = 1023686
- 457 + 1023229 = 1023686
Showing the first eight; more decompositions exist.
