Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978518, here are decompositions:

7 + 978511 = 978518
61 + 978457 = 978518
181 + 978337 = 978518
241 + 978277 = 978518
337 + 978181 = 978518
367 + 978151 = 978518
439 + 978079 = 978518
487 + 978031 = 978518

Showing the first eight; more decompositions exist.
