Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18522, here are decompositions:

5 + 18517 = 18522
19 + 18503 = 18522
29 + 18493 = 18522
41 + 18481 = 18522
61 + 18461 = 18522
71 + 18451 = 18522
79 + 18443 = 18522
83 + 18439 = 18522

Showing the first eight; more decompositions exist.
