Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978384, here are decompositions:

37 + 978347 = 978384
41 + 978343 = 978384
47 + 978337 = 978384
61 + 978323 = 978384
97 + 978287 = 978384
101 + 978283 = 978384
107 + 978277 = 978384
151 + 978233 = 978384

Showing the first eight; more decompositions exist.
