Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978588, here are decompositions:

19 + 978569 = 978588
47 + 978541 = 978588
67 + 978521 = 978588
97 + 978491 = 978588
109 + 978479 = 978588
131 + 978457 = 978588
139 + 978449 = 978588
199 + 978389 = 978588

Showing the first eight; more decompositions exist.
