Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19006, here are decompositions:

5 + 19001 = 19006
47 + 18959 = 19006
59 + 18947 = 19006
89 + 18917 = 19006
107 + 18899 = 19006
137 + 18869 = 19006
167 + 18839 = 19006
233 + 18773 = 19006

Showing the first eight; more decompositions exist.
