Goldbach decomposition

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.
