Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19450, here are decompositions:

3 + 19447 = 19450
17 + 19433 = 19450
23 + 19427 = 19450
29 + 19421 = 19450
47 + 19403 = 19450
59 + 19391 = 19450
71 + 19379 = 19450
131 + 19319 = 19450

Showing the first eight; more decompositions exist.
