Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991914, here are decompositions:
- 5 + 991909 = 991914
- 13 + 991901 = 991914
- 31 + 991883 = 991914
- 41 + 991873 = 991914
- 43 + 991871 = 991914
- 47 + 991867 = 991914
- 97 + 991817 = 991914
- 103 + 991811 = 991914
Showing the first eight; more decompositions exist.
