Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19488, here are decompositions:

5 + 19483 = 19488
11 + 19477 = 19488
17 + 19471 = 19488
19 + 19469 = 19488
31 + 19457 = 19488
41 + 19447 = 19488
47 + 19441 = 19488
59 + 19429 = 19488

Showing the first eight; more decompositions exist.
