Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22458, here are decompositions:

5 + 22453 = 22458
11 + 22447 = 22458
17 + 22441 = 22458
61 + 22397 = 22458
67 + 22391 = 22458
89 + 22369 = 22458
109 + 22349 = 22458
151 + 22307 = 22458

Showing the first eight; more decompositions exist.
