Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2004, here are decompositions:
- 5 + 1999 = 2004
- 7 + 1997 = 2004
- 11 + 1993 = 2004
- 17 + 1987 = 2004
- 31 + 1973 = 2004
- 53 + 1951 = 2004
- 71 + 1933 = 2004
- 73 + 1931 = 2004
Showing the first eight; more decompositions exist.
