Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1066, here are decompositions:
- 3 + 1063 = 1066
- 5 + 1061 = 1066
- 17 + 1049 = 1066
- 47 + 1019 = 1066
- 53 + 1013 = 1066
- 83 + 983 = 1066
- 89 + 977 = 1066
- 113 + 953 = 1066
Showing the first eight; more decompositions exist.
