Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981098, here are decompositions:

7 + 981091 = 981098
31 + 981067 = 981098
37 + 981061 = 981098
61 + 981037 = 981098
199 + 980899 = 981098
211 + 980887 = 981098
271 + 980827 = 981098
367 + 980731 = 981098

Showing the first eight; more decompositions exist.
