Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005856, here are decompositions:

23 + 1005833 = 1005856
29 + 1005827 = 1005856
179 + 1005677 = 1005856
239 + 1005617 = 1005856
263 + 1005593 = 1005856
353 + 1005503 = 1005856
389 + 1005467 = 1005856
419 + 1005437 = 1005856

Showing the first eight; more decompositions exist.
