Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22618, here are decompositions:

5 + 22613 = 22618
47 + 22571 = 22618
107 + 22511 = 22618
137 + 22481 = 22618
149 + 22469 = 22618
227 + 22391 = 22618
251 + 22367 = 22618
269 + 22349 = 22618

Showing the first eight; more decompositions exist.
