Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978862, here are decompositions:

11 + 978851 = 978862
23 + 978839 = 978862
41 + 978821 = 978862
89 + 978773 = 978862
113 + 978749 = 978862
149 + 978713 = 978862
173 + 978689 = 978862
179 + 978683 = 978862

Showing the first eight; more decompositions exist.
