Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005844, here are decompositions:

11 + 1005833 = 1005844
17 + 1005827 = 1005844
23 + 1005821 = 1005844
83 + 1005761 = 1005844
167 + 1005677 = 1005844
197 + 1005647 = 1005844
227 + 1005617 = 1005844
251 + 1005593 = 1005844

Showing the first eight; more decompositions exist.
