Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19026, here are decompositions:

13 + 19013 = 19026
17 + 19009 = 19026
47 + 18979 = 19026
53 + 18973 = 19026
67 + 18959 = 19026
79 + 18947 = 19026
107 + 18919 = 19026
109 + 18917 = 19026

Showing the first eight; more decompositions exist.
