Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19530, here are decompositions:

23 + 19507 = 19530
29 + 19501 = 19530
41 + 19489 = 19530
47 + 19483 = 19530
53 + 19477 = 19530
59 + 19471 = 19530
61 + 19469 = 19530
67 + 19463 = 19530

Showing the first eight; more decompositions exist.
