Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978622, here are decompositions:

3 + 978619 = 978622
5 + 978617 = 978622
11 + 978611 = 978622
23 + 978599 = 978622
53 + 978569 = 978622
101 + 978521 = 978622
131 + 978491 = 978622
149 + 978473 = 978622

Showing the first eight; more decompositions exist.
