Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19492, here are decompositions:

3 + 19489 = 19492
23 + 19469 = 19492
29 + 19463 = 19492
59 + 19433 = 19492
71 + 19421 = 19492
89 + 19403 = 19492
101 + 19391 = 19492
113 + 19379 = 19492

Showing the first eight; more decompositions exist.
