Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997942, here are decompositions:
- 53 + 997889 = 997942
- 131 + 997811 = 997942
- 149 + 997793 = 997942
- 173 + 997769 = 997942
- 191 + 997751 = 997942
- 293 + 997649 = 997942
- 353 + 997589 = 997942
- 359 + 997583 = 997942
Showing the first eight; more decompositions exist.
