Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994878, here are decompositions:

7 + 994871 = 994878
11 + 994867 = 994878
41 + 994837 = 994878
47 + 994831 = 994878
61 + 994817 = 994878
67 + 994811 = 994878
109 + 994769 = 994878
127 + 994751 = 994878

Showing the first eight; more decompositions exist.
