Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978654, here are decompositions:

7 + 978647 = 978654
11 + 978643 = 978654
37 + 978617 = 978654
43 + 978611 = 978654
113 + 978541 = 978654
163 + 978491 = 978654
181 + 978473 = 978654
191 + 978463 = 978654

Showing the first eight; more decompositions exist.
