Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978658, here are decompositions:

11 + 978647 = 978658
41 + 978617 = 978658
47 + 978611 = 978658
59 + 978599 = 978658
89 + 978569 = 978658
137 + 978521 = 978658
167 + 978491 = 978658
179 + 978479 = 978658

Showing the first eight; more decompositions exist.
