Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19494, here are decompositions:

5 + 19489 = 19494
11 + 19483 = 19494
17 + 19477 = 19494
23 + 19471 = 19494
31 + 19463 = 19494
37 + 19457 = 19494
47 + 19447 = 19494
53 + 19441 = 19494

Showing the first eight; more decompositions exist.
