Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021384, here are decompositions:
- 3 + 1021381 = 1021384
- 11 + 1021373 = 1021384
- 17 + 1021367 = 1021384
- 53 + 1021331 = 1021384
- 83 + 1021301 = 1021384
- 101 + 1021283 = 1021384
- 113 + 1021271 = 1021384
- 131 + 1021253 = 1021384
Showing the first eight; more decompositions exist.
