Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997740, here are decompositions:
- 13 + 997727 = 997740
- 41 + 997699 = 997740
- 47 + 997693 = 997740
- 59 + 997681 = 997740
- 89 + 997651 = 997740
- 103 + 997637 = 997740
- 113 + 997627 = 997740
- 131 + 997609 = 997740
Showing the first eight; more decompositions exist.
