Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978506, here are decompositions:

43 + 978463 = 978506
79 + 978427 = 978506
103 + 978403 = 978506
157 + 978349 = 978506
163 + 978343 = 978506
223 + 978283 = 978506
229 + 978277 = 978506
283 + 978223 = 978506

Showing the first eight; more decompositions exist.
