Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982878, here are decompositions:

7 + 982871 = 982878
11 + 982867 = 982878
31 + 982847 = 982878
37 + 982841 = 982878
59 + 982819 = 982878
89 + 982789 = 982878
101 + 982777 = 982878
109 + 982769 = 982878

Showing the first eight; more decompositions exist.
