Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019912, here are decompositions:

13 + 1019899 = 1019912
73 + 1019839 = 1019912
181 + 1019731 = 1019912
199 + 1019713 = 1019912
211 + 1019701 = 1019912
349 + 1019563 = 1019912
379 + 1019533 = 1019912
409 + 1019503 = 1019912

Showing the first eight; more decompositions exist.
