Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966, here are decompositions:
- 13 + 953 = 966
- 19 + 947 = 966
- 29 + 937 = 966
- 37 + 929 = 966
- 47 + 919 = 966
- 59 + 907 = 966
- 79 + 887 = 966
- 83 + 883 = 966
Showing the first eight; more decompositions exist.
