Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6404, here are decompositions:
- 7 + 6397 = 6404
- 31 + 6373 = 6404
- 37 + 6367 = 6404
- 43 + 6361 = 6404
- 61 + 6343 = 6404
- 67 + 6337 = 6404
- 103 + 6301 = 6404
- 127 + 6277 = 6404
Showing the first eight; more decompositions exist.
