Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22454, here are decompositions:

7 + 22447 = 22454
13 + 22441 = 22454
73 + 22381 = 22454
151 + 22303 = 22454
163 + 22291 = 22454
181 + 22273 = 22454
283 + 22171 = 22454
307 + 22147 = 22454

Showing the first eight; more decompositions exist.
