Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005886, here are decompositions:

3 + 1005883 = 1005886
53 + 1005833 = 1005886
59 + 1005827 = 1005886
239 + 1005647 = 1005886
269 + 1005617 = 1005886
293 + 1005593 = 1005886
359 + 1005527 = 1005886
383 + 1005503 = 1005886

Showing the first eight; more decompositions exist.
