Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18548, here are decompositions:

7 + 18541 = 18548
31 + 18517 = 18548
67 + 18481 = 18548
97 + 18451 = 18548
109 + 18439 = 18548
151 + 18397 = 18548
181 + 18367 = 18548
241 + 18307 = 18548

Showing the first eight; more decompositions exist.
