Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18498, here are decompositions:

5 + 18493 = 18498
17 + 18481 = 18498
37 + 18461 = 18498
41 + 18457 = 18498
47 + 18451 = 18498
59 + 18439 = 18498
71 + 18427 = 18498
97 + 18401 = 18498

Showing the first eight; more decompositions exist.
