Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006578, here are decompositions:

19 + 1006559 = 1006578
31 + 1006547 = 1006578
47 + 1006531 = 1006578
71 + 1006507 = 1006578
107 + 1006471 = 1006578
109 + 1006469 = 1006578
137 + 1006441 = 1006578
211 + 1006367 = 1006578

Showing the first eight; more decompositions exist.
