Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000998, here are decompositions:
- 17 + 1000981 = 1000998
- 29 + 1000969 = 1000998
- 67 + 1000931 = 1000998
- 79 + 1000919 = 1000998
- 109 + 1000889 = 1000998
- 137 + 1000861 = 1000998
- 139 + 1000859 = 1000998
- 149 + 1000849 = 1000998
Showing the first eight; more decompositions exist.
