Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997750, here are decompositions:
- 11 + 997739 = 997750
- 23 + 997727 = 997750
- 101 + 997649 = 997750
- 113 + 997637 = 997750
- 167 + 997583 = 997750
- 197 + 997553 = 997750
- 239 + 997511 = 997750
- 311 + 997439 = 997750
Showing the first eight; more decompositions exist.
