Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18348, here are decompositions:

7 + 18341 = 18348
19 + 18329 = 18348
37 + 18311 = 18348
41 + 18307 = 18348
47 + 18301 = 18348
59 + 18289 = 18348
61 + 18287 = 18348
79 + 18269 = 18348

Showing the first eight; more decompositions exist.
