Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998844, here are decompositions:
- 5 + 998839 = 998844
- 13 + 998831 = 998844
- 31 + 998813 = 998844
- 101 + 998743 = 998844
- 107 + 998737 = 998844
- 127 + 998717 = 998844
- 157 + 998687 = 998844
- 163 + 998681 = 998844
Showing the first eight; more decompositions exist.
