Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978732, here are decompositions:

5 + 978727 = 978732
19 + 978713 = 978732
43 + 978689 = 978732
89 + 978643 = 978732
113 + 978619 = 978732
163 + 978569 = 978732
191 + 978541 = 978732
211 + 978521 = 978732

Showing the first eight; more decompositions exist.
