Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978886, here are decompositions:

3 + 978883 = 978886
23 + 978863 = 978886
47 + 978839 = 978886
89 + 978797 = 978886
113 + 978773 = 978886
137 + 978749 = 978886
173 + 978713 = 978886
197 + 978689 = 978886

Showing the first eight; more decompositions exist.
