Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978766, here are decompositions:

17 + 978749 = 978766
23 + 978743 = 978766
53 + 978713 = 978766
83 + 978683 = 978766
149 + 978617 = 978766
167 + 978599 = 978766
197 + 978569 = 978766
293 + 978473 = 978766

Showing the first eight; more decompositions exist.
