Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978540, here are decompositions:

19 + 978521 = 978540
29 + 978511 = 978540
61 + 978479 = 978540
67 + 978473 = 978540
83 + 978457 = 978540
113 + 978427 = 978540
127 + 978413 = 978540
137 + 978403 = 978540

Showing the first eight; more decompositions exist.
