Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019906, here are decompositions:

3 + 1019903 = 1019906
7 + 1019899 = 1019906
67 + 1019839 = 1019906
79 + 1019827 = 1019906
193 + 1019713 = 1019906
373 + 1019533 = 1019906
397 + 1019509 = 1019906
439 + 1019467 = 1019906

Showing the first eight; more decompositions exist.
