Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978810, here are decompositions:

11 + 978799 = 978810
13 + 978797 = 978810
37 + 978773 = 978810
61 + 978749 = 978810
67 + 978743 = 978810
83 + 978727 = 978810
97 + 978713 = 978810
113 + 978697 = 978810

Showing the first eight; more decompositions exist.
