Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001856, here are decompositions:

17 + 1001839 = 1001856
47 + 1001809 = 1001856
59 + 1001797 = 1001856
73 + 1001783 = 1001856
113 + 1001743 = 1001856
173 + 1001683 = 1001856
197 + 1001659 = 1001856
227 + 1001629 = 1001856

Showing the first eight; more decompositions exist.
