Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981074, here are decompositions:

7 + 981067 = 981074
13 + 981061 = 981074
37 + 981037 = 981074
163 + 980911 = 981074
181 + 980893 = 981074
223 + 980851 = 981074
271 + 980803 = 981074
397 + 980677 = 981074

Showing the first eight; more decompositions exist.
