Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978558, here are decompositions:

17 + 978541 = 978558
37 + 978521 = 978558
47 + 978511 = 978558
67 + 978491 = 978558
79 + 978479 = 978558
101 + 978457 = 978558
109 + 978449 = 978558
131 + 978427 = 978558

Showing the first eight; more decompositions exist.
