Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22286, here are decompositions:

3 + 22283 = 22286
7 + 22279 = 22286
13 + 22273 = 22286
97 + 22189 = 22286
127 + 22159 = 22286
139 + 22147 = 22286
157 + 22129 = 22286
163 + 22123 = 22286

Showing the first eight; more decompositions exist.
