Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003998, here are decompositions:
- 41 + 1003957 = 1003998
- 67 + 1003931 = 1003998
- 89 + 1003909 = 1003998
- 101 + 1003897 = 1003998
- 109 + 1003889 = 1003998
- 157 + 1003841 = 1003998
- 179 + 1003819 = 1003998
- 181 + 1003817 = 1003998
Showing the first eight; more decompositions exist.
