Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2006, here are decompositions:
- 3 + 2003 = 2006
- 7 + 1999 = 2006
- 13 + 1993 = 2006
- 19 + 1987 = 2006
- 73 + 1933 = 2006
- 127 + 1879 = 2006
- 139 + 1867 = 2006
- 223 + 1783 = 2006
Showing the first eight; more decompositions exist.
