Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19480, here are decompositions:

3 + 19477 = 19480
11 + 19469 = 19480
17 + 19463 = 19480
23 + 19457 = 19480
47 + 19433 = 19480
53 + 19427 = 19480
59 + 19421 = 19480
89 + 19391 = 19480

Showing the first eight; more decompositions exist.
