Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19020, here are decompositions:

7 + 19013 = 19020
11 + 19009 = 19020
19 + 19001 = 19020
41 + 18979 = 19020
47 + 18973 = 19020
61 + 18959 = 19020
73 + 18947 = 19020
101 + 18919 = 19020

Showing the first eight; more decompositions exist.
