Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005658, here are decompositions:

11 + 1005647 = 1005658
41 + 1005617 = 1005658
107 + 1005551 = 1005658
131 + 1005527 = 1005658
191 + 1005467 = 1005658
389 + 1005269 = 1005658
419 + 1005239 = 1005658
449 + 1005209 = 1005658

Showing the first eight; more decompositions exist.
