Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009886, here are decompositions:

13 + 1009873 = 1009886
43 + 1009843 = 1009886
67 + 1009819 = 1009886
79 + 1009807 = 1009886
139 + 1009747 = 1009886
277 + 1009609 = 1009886
313 + 1009573 = 1009886
349 + 1009537 = 1009886

Showing the first eight; more decompositions exist.
