Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978486, here are decompositions:

7 + 978479 = 978486
13 + 978473 = 978486
23 + 978463 = 978486
29 + 978457 = 978486
37 + 978449 = 978486
59 + 978427 = 978486
73 + 978413 = 978486
83 + 978403 = 978486

Showing the first eight; more decompositions exist.
