Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978790, here are decompositions:

17 + 978773 = 978790
41 + 978749 = 978790
47 + 978743 = 978790
101 + 978689 = 978790
107 + 978683 = 978790
173 + 978617 = 978790
179 + 978611 = 978790
191 + 978599 = 978790

Showing the first eight; more decompositions exist.
