Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987116, here are decompositions:

19 + 987097 = 987116
37 + 987079 = 987116
73 + 987043 = 987116
103 + 987013 = 987116
127 + 986989 = 987116
157 + 986959 = 987116
337 + 986779 = 987116
349 + 986767 = 987116

Showing the first eight; more decompositions exist.
