Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998680, here are decompositions:
- 29 + 998651 = 998680
- 47 + 998633 = 998680
- 167 + 998513 = 998680
- 251 + 998429 = 998680
- 257 + 998423 = 998680
- 269 + 998411 = 998680
- 281 + 998399 = 998680
- 443 + 998237 = 998680
Showing the first eight; more decompositions exist.
