Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19504, here are decompositions:

3 + 19501 = 19504
41 + 19463 = 19504
47 + 19457 = 19504
71 + 19433 = 19504
83 + 19421 = 19504
101 + 19403 = 19504
113 + 19391 = 19504
131 + 19373 = 19504

Showing the first eight; more decompositions exist.
