Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19266, here are decompositions:

7 + 19259 = 19266
17 + 19249 = 19266
29 + 19237 = 19266
47 + 19219 = 19266
53 + 19213 = 19266
59 + 19207 = 19266
83 + 19183 = 19266
103 + 19163 = 19266

Showing the first eight; more decompositions exist.
