Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19022, here are decompositions:

13 + 19009 = 19022
43 + 18979 = 19022
103 + 18919 = 19022
109 + 18913 = 19022
163 + 18859 = 19022
229 + 18793 = 19022
331 + 18691 = 19022
439 + 18583 = 19022

Showing the first eight; more decompositions exist.
