Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998460, here are decompositions:
- 17 + 998443 = 998460
- 31 + 998429 = 998460
- 37 + 998423 = 998460
- 41 + 998419 = 998460
- 61 + 998399 = 998460
- 79 + 998381 = 998460
- 83 + 998377 = 998460
- 107 + 998353 = 998460
Showing the first eight; more decompositions exist.
