Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019828, here are decompositions:

97 + 1019731 = 1019828
127 + 1019701 = 1019828
181 + 1019647 = 1019828
211 + 1019617 = 1019828
349 + 1019479 = 1019828
379 + 1019449 = 1019828
499 + 1019329 = 1019828
547 + 1019281 = 1019828

Showing the first eight; more decompositions exist.
