Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19544, here are decompositions:

3 + 19541 = 19544
13 + 19531 = 19544
37 + 19507 = 19544
43 + 19501 = 19544
61 + 19483 = 19544
67 + 19477 = 19544
73 + 19471 = 19544
97 + 19447 = 19544

Showing the first eight; more decompositions exist.
