Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005580, here are decompositions:
- 29 + 1005551 = 1005580
- 53 + 1005527 = 1005580
- 113 + 1005467 = 1005580
- 167 + 1005413 = 1005580
- 263 + 1005317 = 1005580
- 293 + 1005287 = 1005580
- 311 + 1005269 = 1005580
- 419 + 1005161 = 1005580
Showing the first eight; more decompositions exist.
