Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048320, here are decompositions:
- 11 + 1048309 = 1048320
- 29 + 1048291 = 1048320
- 47 + 1048273 = 1048320
- 59 + 1048261 = 1048320
- 101 + 1048219 = 1048320
- 103 + 1048217 = 1048320
- 107 + 1048213 = 1048320
- 127 + 1048193 = 1048320
Showing the first eight; more decompositions exist.
