Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15498, here are decompositions:

5 + 15493 = 15498
31 + 15467 = 15498
37 + 15461 = 15498
47 + 15451 = 15498
59 + 15439 = 15498
71 + 15427 = 15498
97 + 15401 = 15498
107 + 15391 = 15498

Showing the first eight; more decompositions exist.
