Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19130, here are decompositions:

43 + 19087 = 19130
61 + 19069 = 19130
79 + 19051 = 19130
151 + 18979 = 19130
157 + 18973 = 19130
211 + 18919 = 19130
271 + 18859 = 19130
337 + 18793 = 19130

Showing the first eight; more decompositions exist.
