Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19224, here are decompositions:

5 + 19219 = 19224
11 + 19213 = 19224
13 + 19211 = 19224
17 + 19207 = 19224
41 + 19183 = 19224
43 + 19181 = 19224
61 + 19163 = 19224
67 + 19157 = 19224

Showing the first eight; more decompositions exist.
