Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978624, here are decompositions:

5 + 978619 = 978624
7 + 978617 = 978624
13 + 978611 = 978624
83 + 978541 = 978624
103 + 978521 = 978624
113 + 978511 = 978624
151 + 978473 = 978624
167 + 978457 = 978624

Showing the first eight; more decompositions exist.
