Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978970, here are decompositions:

23 + 978947 = 978970
53 + 978917 = 978970
107 + 978863 = 978970
131 + 978839 = 978970
149 + 978821 = 978970
173 + 978797 = 978970
197 + 978773 = 978970
227 + 978743 = 978970

Showing the first eight; more decompositions exist.
