Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18354, here are decompositions:

13 + 18341 = 18354
41 + 18313 = 18354
43 + 18311 = 18354
47 + 18307 = 18354
53 + 18301 = 18354
67 + 18287 = 18354
97 + 18257 = 18354
101 + 18253 = 18354

Showing the first eight; more decompositions exist.
