Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997906, here are decompositions:
- 17 + 997889 = 997906
- 29 + 997877 = 997906
- 113 + 997793 = 997906
- 137 + 997769 = 997906
- 167 + 997739 = 997906
- 179 + 997727 = 997906
- 257 + 997649 = 997906
- 269 + 997637 = 997906
Showing the first eight; more decompositions exist.
