Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978516, here are decompositions:

5 + 978511 = 978516
37 + 978479 = 978516
43 + 978473 = 978516
53 + 978463 = 978516
59 + 978457 = 978516
67 + 978449 = 978516
89 + 978427 = 978516
103 + 978413 = 978516

Showing the first eight; more decompositions exist.
