Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998860, here are decompositions:
- 3 + 998857 = 998860
- 17 + 998843 = 998860
- 29 + 998831 = 998860
- 41 + 998819 = 998860
- 47 + 998813 = 998860
- 101 + 998759 = 998860
- 173 + 998687 = 998860
- 179 + 998681 = 998860
Showing the first eight; more decompositions exist.
