Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978446, here are decompositions:

19 + 978427 = 978446
43 + 978403 = 978446
97 + 978349 = 978446
103 + 978343 = 978446
109 + 978337 = 978446
163 + 978283 = 978446
223 + 978223 = 978446
229 + 978217 = 978446

Showing the first eight; more decompositions exist.
