Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978838, here are decompositions:

17 + 978821 = 978838
41 + 978797 = 978838
89 + 978749 = 978838
149 + 978689 = 978838
191 + 978647 = 978838
227 + 978611 = 978838
239 + 978599 = 978838
269 + 978569 = 978838

Showing the first eight; more decompositions exist.
