Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978858, here are decompositions:

5 + 978853 = 978858
7 + 978851 = 978858
19 + 978839 = 978858
37 + 978821 = 978858
59 + 978799 = 978858
61 + 978797 = 978858
109 + 978749 = 978858
131 + 978727 = 978858

Showing the first eight; more decompositions exist.
