Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006878, here are decompositions:

17 + 1006861 = 1006878
31 + 1006847 = 1006878
79 + 1006799 = 1006878
97 + 1006781 = 1006878
109 + 1006769 = 1006878
127 + 1006751 = 1006878
139 + 1006739 = 1006878
157 + 1006721 = 1006878

Showing the first eight; more decompositions exist.
