Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048878, here are decompositions:

11 + 1048867 = 1048878
31 + 1048847 = 1048878
41 + 1048837 = 1048878
71 + 1048807 = 1048878
79 + 1048799 = 1048878
157 + 1048721 = 1048878
197 + 1048681 = 1048878
251 + 1048627 = 1048878

Showing the first eight; more decompositions exist.
