Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22436, here are decompositions:

3 + 22433 = 22436
67 + 22369 = 22436
157 + 22279 = 22436
163 + 22273 = 22436
277 + 22159 = 22436
283 + 22153 = 22436
307 + 22129 = 22436
313 + 22123 = 22436

Showing the first eight; more decompositions exist.
