Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997992, here are decompositions:
- 19 + 997973 = 997992
- 29 + 997963 = 997992
- 31 + 997961 = 997992
- 43 + 997949 = 997992
- 59 + 997933 = 997992
- 101 + 997891 = 997992
- 103 + 997889 = 997992
- 113 + 997879 = 997992
Showing the first eight; more decompositions exist.
