Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19012, here are decompositions:

3 + 19009 = 19012
11 + 19001 = 19012
53 + 18959 = 19012
101 + 18911 = 19012
113 + 18899 = 19012
173 + 18839 = 19012
239 + 18773 = 19012
263 + 18749 = 19012

Showing the first eight; more decompositions exist.
