Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19506, here are decompositions:

5 + 19501 = 19506
17 + 19489 = 19506
23 + 19483 = 19506
29 + 19477 = 19506
37 + 19469 = 19506
43 + 19463 = 19506
59 + 19447 = 19506
73 + 19433 = 19506

Showing the first eight; more decompositions exist.
