Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981026, here are decompositions:

3 + 981023 = 981026
127 + 980899 = 981026
139 + 980887 = 981026
199 + 980827 = 981026
223 + 980803 = 981026
307 + 980719 = 981026
337 + 980689 = 981026
349 + 980677 = 981026

Showing the first eight; more decompositions exist.
