Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964, here are decompositions:
- 11 + 953 = 964
- 17 + 947 = 964
- 23 + 941 = 964
- 53 + 911 = 964
- 83 + 881 = 964
- 101 + 863 = 964
- 107 + 857 = 964
- 137 + 827 = 964
Showing the first eight; more decompositions exist.
