Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8964, here are decompositions:
- 13 + 8951 = 8964
- 23 + 8941 = 8964
- 31 + 8933 = 8964
- 41 + 8923 = 8964
- 71 + 8893 = 8964
- 97 + 8867 = 8964
- 101 + 8863 = 8964
- 103 + 8861 = 8964
Showing the first eight; more decompositions exist.
