Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978566, here are decompositions:

103 + 978463 = 978566
109 + 978457 = 978566
139 + 978427 = 978566
163 + 978403 = 978566
223 + 978343 = 978566
229 + 978337 = 978566
283 + 978283 = 978566
349 + 978217 = 978566

Showing the first eight; more decompositions exist.
