Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019640, here are decompositions:

23 + 1019617 = 1019640
103 + 1019537 = 1019640
107 + 1019533 = 1019640
109 + 1019531 = 1019640
131 + 1019509 = 1019640
137 + 1019503 = 1019640
173 + 1019467 = 1019640
191 + 1019449 = 1019640

Showing the first eight; more decompositions exist.
