Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991082, here are decompositions:

3 + 991079 = 991082
13 + 991069 = 991082
19 + 991063 = 991082
73 + 991009 = 991082
109 + 990973 = 991082
193 + 990889 = 991082
241 + 990841 = 991082
283 + 990799 = 991082

Showing the first eight; more decompositions exist.
