Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981056, here are decompositions:

7 + 981049 = 981056
19 + 981037 = 981056
157 + 980899 = 981056
163 + 980893 = 981056
229 + 980827 = 981056
283 + 980773 = 981056
337 + 980719 = 981056
367 + 980689 = 981056

Showing the first eight; more decompositions exist.
