Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998730, here are decompositions:
- 13 + 998717 = 998730
- 41 + 998689 = 998730
- 43 + 998687 = 998730
- 79 + 998651 = 998730
- 97 + 998633 = 998730
- 101 + 998629 = 998730
- 107 + 998623 = 998730
- 113 + 998617 = 998730
Showing the first eight; more decompositions exist.
