Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007998, here are decompositions:

41 + 1007957 = 1007998
59 + 1007939 = 1007998
107 + 1007891 = 1007998
137 + 1007861 = 1007998
179 + 1007819 = 1007998
191 + 1007807 = 1007998
197 + 1007801 = 1007998
227 + 1007771 = 1007998

Showing the first eight; more decompositions exist.
