Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019372, here are decompositions:

19 + 1019353 = 1019372
43 + 1019329 = 1019372
163 + 1019209 = 1019372
199 + 1019173 = 1019372
313 + 1019059 = 1019372
349 + 1019023 = 1019372
373 + 1018999 = 1019372
379 + 1018993 = 1019372

Showing the first eight; more decompositions exist.
