Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050640, here are decompositions:

29 + 1050611 = 1050640
47 + 1050593 = 1050640
131 + 1050509 = 1050640
137 + 1050503 = 1050640
167 + 1050473 = 1050640
191 + 1050449 = 1050640
317 + 1050323 = 1050640
359 + 1050281 = 1050640

Showing the first eight; more decompositions exist.
