Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057540, here are decompositions:
- 47 + 1057493 = 1057540
- 53 + 1057487 = 1057540
- 149 + 1057391 = 1057540
- 173 + 1057367 = 1057540
- 179 + 1057361 = 1057540
- 233 + 1057307 = 1057540
- 269 + 1057271 = 1057540
- 317 + 1057223 = 1057540
Showing the first eight; more decompositions exist.
