Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2066, here are decompositions:
- 3 + 2063 = 2066
- 13 + 2053 = 2066
- 37 + 2029 = 2066
- 67 + 1999 = 2066
- 73 + 1993 = 2066
- 79 + 1987 = 2066
- 193 + 1873 = 2066
- 199 + 1867 = 2066
Showing the first eight; more decompositions exist.
