Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997974, here are decompositions:
- 11 + 997963 = 997974
- 13 + 997961 = 997974
- 41 + 997933 = 997974
- 83 + 997891 = 997974
- 97 + 997877 = 997974
- 163 + 997811 = 997974
- 167 + 997807 = 997974
- 181 + 997793 = 997974
Showing the first eight; more decompositions exist.
