Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19604, here are decompositions:

7 + 19597 = 19604
61 + 19543 = 19604
73 + 19531 = 19604
97 + 19507 = 19604
103 + 19501 = 19604
127 + 19477 = 19604
157 + 19447 = 19604
163 + 19441 = 19604

Showing the first eight; more decompositions exist.
