Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978524, here are decompositions:

3 + 978521 = 978524
13 + 978511 = 978524
61 + 978463 = 978524
67 + 978457 = 978524
97 + 978427 = 978524
181 + 978343 = 978524
241 + 978283 = 978524
307 + 978217 = 978524

Showing the first eight; more decompositions exist.
