Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978480, here are decompositions:

7 + 978473 = 978480
17 + 978463 = 978480
23 + 978457 = 978480
31 + 978449 = 978480
53 + 978427 = 978480
67 + 978413 = 978480
131 + 978349 = 978480
137 + 978343 = 978480

Showing the first eight; more decompositions exist.
