Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978844, here are decompositions:

5 + 978839 = 978844
23 + 978821 = 978844
47 + 978797 = 978844
71 + 978773 = 978844
101 + 978743 = 978844
131 + 978713 = 978844
197 + 978647 = 978844
227 + 978617 = 978844

Showing the first eight; more decompositions exist.
