Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66404, here are decompositions:
- 31 + 66373 = 66404
- 43 + 66361 = 66404
- 61 + 66343 = 66404
- 67 + 66337 = 66404
- 103 + 66301 = 66404
- 337 + 66067 = 66404
- 367 + 66037 = 66404
- 421 + 65983 = 66404
Showing the first eight; more decompositions exist.
