Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981050, here are decompositions:

13 + 981037 = 981050
139 + 980911 = 981050
151 + 980899 = 981050
157 + 980893 = 981050
163 + 980887 = 981050
199 + 980851 = 981050
223 + 980827 = 981050
277 + 980773 = 981050

Showing the first eight; more decompositions exist.
