Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978866, here are decompositions:

3 + 978863 = 978866
13 + 978853 = 978866
67 + 978799 = 978866
139 + 978727 = 978866
223 + 978643 = 978866
409 + 978457 = 978866
439 + 978427 = 978866
463 + 978403 = 978866

Showing the first eight; more decompositions exist.
