Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20004, here are decompositions:
- 7 + 19997 = 20004
- 11 + 19993 = 20004
- 13 + 19991 = 20004
- 31 + 19973 = 20004
- 41 + 19963 = 20004
- 43 + 19961 = 20004
- 67 + 19937 = 20004
- 113 + 19891 = 20004
Showing the first eight; more decompositions exist.
