Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19000, here are decompositions:

41 + 18959 = 19000
53 + 18947 = 19000
83 + 18917 = 19000
89 + 18911 = 19000
101 + 18899 = 19000
131 + 18869 = 19000
197 + 18803 = 19000
227 + 18773 = 19000

Showing the first eight; more decompositions exist.
