Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978450, here are decompositions:

23 + 978427 = 978450
37 + 978413 = 978450
47 + 978403 = 978450
61 + 978389 = 978450
101 + 978349 = 978450
103 + 978347 = 978450
107 + 978343 = 978450
113 + 978337 = 978450

Showing the first eight; more decompositions exist.
