Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22408, here are decompositions:

11 + 22397 = 22408
17 + 22391 = 22408
41 + 22367 = 22408
59 + 22349 = 22408
101 + 22307 = 22408
131 + 22277 = 22408
137 + 22271 = 22408
149 + 22259 = 22408

Showing the first eight; more decompositions exist.
