Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978630, here are decompositions:

11 + 978619 = 978630
13 + 978617 = 978630
19 + 978611 = 978630
31 + 978599 = 978630
61 + 978569 = 978630
89 + 978541 = 978630
109 + 978521 = 978630
139 + 978491 = 978630

Showing the first eight; more decompositions exist.
