Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64404, here are decompositions:
- 5 + 64399 = 64404
- 23 + 64381 = 64404
- 31 + 64373 = 64404
- 71 + 64333 = 64404
- 101 + 64303 = 64404
- 103 + 64301 = 64404
- 167 + 64237 = 64404
- 173 + 64231 = 64404
Showing the first eight; more decompositions exist.
