Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20522, here are decompositions:

13 + 20509 = 20522
43 + 20479 = 20522
79 + 20443 = 20522
163 + 20359 = 20522
181 + 20341 = 20522
199 + 20323 = 20522
349 + 20173 = 20522
373 + 20149 = 20522

Showing the first eight; more decompositions exist.
