Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981992, here are decompositions:

13 + 981979 = 981992
31 + 981961 = 981992
43 + 981949 = 981992
73 + 981919 = 981992
79 + 981913 = 981992
103 + 981889 = 981992
181 + 981811 = 981992
223 + 981769 = 981992

Showing the first eight; more decompositions exist.
