Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990284, here are decompositions:
- 3 + 990281 = 990284
- 7 + 990277 = 990284
- 73 + 990211 = 990284
- 103 + 990181 = 990284
- 241 + 990043 = 990284
- 271 + 990013 = 990284
- 283 + 990001 = 990284
- 307 + 989977 = 990284
Showing the first eight; more decompositions exist.
