Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005688, here are decompositions:

11 + 1005677 = 1005688
41 + 1005647 = 1005688
71 + 1005617 = 1005688
107 + 1005581 = 1005688
137 + 1005551 = 1005688
251 + 1005437 = 1005688
317 + 1005371 = 1005688
401 + 1005287 = 1005688

Showing the first eight; more decompositions exist.
