Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978876, here are decompositions:

5 + 978871 = 978876
13 + 978863 = 978876
23 + 978853 = 978876
37 + 978839 = 978876
79 + 978797 = 978876
103 + 978773 = 978876
127 + 978749 = 978876
149 + 978727 = 978876

Showing the first eight; more decompositions exist.
