Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981006, here are decompositions:

7 + 980999 = 981006
43 + 980963 = 981006
97 + 980909 = 981006
107 + 980899 = 981006
109 + 980897 = 981006
113 + 980893 = 981006
179 + 980827 = 981006
233 + 980773 = 981006

Showing the first eight; more decompositions exist.
