Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22404, here are decompositions:
- 7 + 22397 = 22404
- 13 + 22391 = 22404
- 23 + 22381 = 22404
- 37 + 22367 = 22404
- 61 + 22343 = 22404
- 97 + 22307 = 22404
- 101 + 22303 = 22404
- 113 + 22291 = 22404
Showing the first eight; more decompositions exist.
