Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978530, here are decompositions:

19 + 978511 = 978530
67 + 978463 = 978530
73 + 978457 = 978530
103 + 978427 = 978530
127 + 978403 = 978530
181 + 978349 = 978530
193 + 978337 = 978530
307 + 978223 = 978530

Showing the first eight; more decompositions exist.
