Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978492, here are decompositions:

13 + 978479 = 978492
19 + 978473 = 978492
29 + 978463 = 978492
43 + 978449 = 978492
79 + 978413 = 978492
89 + 978403 = 978492
103 + 978389 = 978492
149 + 978343 = 978492

Showing the first eight; more decompositions exist.
