Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998842, here are decompositions:
- 3 + 998839 = 998842
- 11 + 998831 = 998842
- 23 + 998819 = 998842
- 29 + 998813 = 998842
- 83 + 998759 = 998842
- 191 + 998651 = 998842
- 281 + 998561 = 998842
- 419 + 998423 = 998842
Showing the first eight; more decompositions exist.
