Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978670, here are decompositions:

23 + 978647 = 978670
53 + 978617 = 978670
59 + 978611 = 978670
71 + 978599 = 978670
101 + 978569 = 978670
149 + 978521 = 978670
179 + 978491 = 978670
191 + 978479 = 978670

Showing the first eight; more decompositions exist.
