Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978464, here are decompositions:

7 + 978457 = 978464
37 + 978427 = 978464
61 + 978403 = 978464
127 + 978337 = 978464
181 + 978283 = 978464
241 + 978223 = 978464
283 + 978181 = 978464
307 + 978157 = 978464

Showing the first eight; more decompositions exist.
