Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981092, here are decompositions:

19 + 981073 = 981092
31 + 981061 = 981092
43 + 981049 = 981092
181 + 980911 = 981092
193 + 980899 = 981092
199 + 980893 = 981092
241 + 980851 = 981092
373 + 980719 = 981092

Showing the first eight; more decompositions exist.
