Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19010, here are decompositions:

31 + 18979 = 19010
37 + 18973 = 19010
97 + 18913 = 19010
151 + 18859 = 19010
223 + 18787 = 19010
331 + 18679 = 19010
349 + 18661 = 19010
373 + 18637 = 19010

Showing the first eight; more decompositions exist.
