Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22516, here are decompositions:

5 + 22511 = 22516
47 + 22469 = 22516
83 + 22433 = 22516
107 + 22409 = 22516
149 + 22367 = 22516
167 + 22349 = 22516
173 + 22343 = 22516
233 + 22283 = 22516

Showing the first eight; more decompositions exist.
