Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019876, here are decompositions:

3 + 1019873 = 1019876
19 + 1019857 = 1019876
37 + 1019839 = 1019876
163 + 1019713 = 1019876
229 + 1019647 = 1019876
313 + 1019563 = 1019876
367 + 1019509 = 1019876
373 + 1019503 = 1019876

Showing the first eight; more decompositions exist.
