Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978528, here are decompositions:

7 + 978521 = 978528
17 + 978511 = 978528
37 + 978491 = 978528
71 + 978457 = 978528
79 + 978449 = 978528
101 + 978427 = 978528
139 + 978389 = 978528
179 + 978349 = 978528

Showing the first eight; more decompositions exist.
