Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19044, here are decompositions:

7 + 19037 = 19044
13 + 19031 = 19044
31 + 19013 = 19044
43 + 19001 = 19044
71 + 18973 = 19044
97 + 18947 = 19044
127 + 18917 = 19044
131 + 18913 = 19044

Showing the first eight; more decompositions exist.
