Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027856, here are decompositions:

3 + 1027853 = 1027856
73 + 1027783 = 1027856
79 + 1027777 = 1027856
97 + 1027759 = 1027856
103 + 1027753 = 1027856
139 + 1027717 = 1027856
163 + 1027693 = 1027856
307 + 1027549 = 1027856

Showing the first eight; more decompositions exist.
