Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978808, here are decompositions:

11 + 978797 = 978808
59 + 978749 = 978808
191 + 978617 = 978808
197 + 978611 = 978808
239 + 978569 = 978808
317 + 978491 = 978808
359 + 978449 = 978808
419 + 978389 = 978808

Showing the first eight; more decompositions exist.
