Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028456, here are decompositions:
- 19 + 1028437 = 1028456
- 67 + 1028389 = 1028456
- 127 + 1028329 = 1028456
- 139 + 1028317 = 1028456
- 193 + 1028263 = 1028456
- 307 + 1028149 = 1028456
- 349 + 1028107 = 1028456
- 367 + 1028089 = 1028456
Showing the first eight; more decompositions exist.
