Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978826, here are decompositions:

5 + 978821 = 978826
29 + 978797 = 978826
53 + 978773 = 978826
83 + 978743 = 978826
113 + 978713 = 978826
137 + 978689 = 978826
179 + 978647 = 978826
227 + 978599 = 978826

Showing the first eight; more decompositions exist.
