Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19498, here are decompositions:

29 + 19469 = 19498
41 + 19457 = 19498
71 + 19427 = 19498
107 + 19391 = 19498
179 + 19319 = 19498
197 + 19301 = 19498
239 + 19259 = 19498
317 + 19181 = 19498

Showing the first eight; more decompositions exist.
