Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996988, here are decompositions:

89 + 996899 = 996988
101 + 996887 = 996988
107 + 996881 = 996988
131 + 996857 = 996988
359 + 996629 = 996988
389 + 996599 = 996988
449 + 996539 = 996988
557 + 996431 = 996988

Showing the first eight; more decompositions exist.
